As bricks are the most essential and widely utilized building materials in the construction industry, the significance of developing an alternate eco-friendly brick is substantial in modern times. In this paper, manufacturing and potential utilization of Fly-ash made building bricks have been studied and was found to be a prospective substitute for fired clay bricks that contribute greatly to polluting the environment. Also, a comparison between sand made and ceramic dust made Fly-ash bricks have been carried out experimentally. The ceramic dust made bricks seem to show higher compressive strength at lower unit volume weight compared to sand made Fly-ash bricks. Moreover, the water absorption capacity of ceramic dust Fly-ash bricks was lower than sand made bricks. Then finally a statistical comparison between fired clay bricks and fly-ash bricks were carried out. All the requirements for good quality building bricks are matched by the fly-ash bricks. All the facts from this study pointed out that these bricks give a new opportunity for being an alternate building material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coal%20fly-ash" title="coal fly-ash">coal fly-ash</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramic%20dust" title=" ceramic dust"> ceramic dust</a>, <a href="https://publications.waset.org/abstracts/search?q=burnt%20clay%20bricks" title=" burnt clay bricks"> burnt clay bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=sand" title=" sand"> sand</a>, <a href="https://publications.waset.org/abstracts/search?q=gypsum" title=" gypsum"> gypsum</a>, <a href="https://publications.waset.org/abstracts/search?q=absorption%20capacity" title=" absorption capacity"> absorption capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=unit%20volume%20weight" title=" unit volume weight"> unit volume weight</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a> </p> <a href="https://publications.waset.org/abstracts/17049/building-bricks-made-of-fly-ash-mixed-with-sand-or-ceramic-dust-synthesis-and-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17049.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">422</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">682</span> An Overview of Sludge Utilization into Fired Clay Brick</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aeslina%20Binti%20Abdul%20Kadir">Aeslina Binti Abdul Kadir</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Shayuti%20Bin%20Abdul%20Rahim"> Ahmad Shayuti Bin Abdul Rahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brick is one of the most common masonry units used as building material. Due to the demand, different types of waste have been investigated to be incorporated into the bricks. Many types of sludge have been incorporated in fired clay brick for example marble sludge, stone sludge, water sludge, sewage sludge, and ceramic sludge. The utilization of these waste materials in fired clay bricks usually has positive effects on the properties such as lightweight bricks with improved shrinkage, porosity, and strength. This paper reviews on utilization of different types of sludge wastes into fired clay bricks. Previous investigations have demonstrated positive effects on the physical and mechanical properties as well as less impact towards the environment. Thus, the utilizations of sludge waste could produce a good quality of brick and could be one of alternative disposal methods for the sludge wastes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fired%20clay%20brick" title="fired clay brick">fired clay brick</a>, <a href="https://publications.waset.org/abstracts/search?q=sludge%20waste" title=" sludge waste"> sludge waste</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=shrinkage" title=" shrinkage"> shrinkage</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20absorption" title=" water absorption"> water absorption</a> </p> <a href="https://publications.waset.org/abstracts/11628/an-overview-of-sludge-utilization-into-fired-clay-brick" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11628.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">446</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">681</span> Properties of Fly Ash Brick Prepared in Local Environment of Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robiul%20Islam">Robiul Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Monjurul%20Hasan"> Monjurul Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rezaul%20Karim"> Rezaul Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20F.%20M.%20Zain"> M.

On the other hand, manufacturing conventional clay bricks involves on consumption of large amount of clay and leads substantial depletion of topsoil. This paper unveils the possibility of using fly ash as a partial replacement of clay for brick manufacturing considering the local technology practiced in Bangladesh. The effect of fly ash with different replacing ratio (0%, 20%, 30%, 40% and 50% by volume) of clay on properties of bricks were studied. Bricks were made in the field parallel to ordinary bricks marked with specific number for different percentage to identify them at time of testing. No physical distortion is observed in fly ash brick after burning in the kiln. Results from laboratory test show that compressive strength of brick is decreased with the increase of fly ash and maximum compressive strength is found to be 19.6 MPa at 20% of fly ash. In addition, water absorption of fly ash brick is increased with the increase of fly ash. The abrasion value and Specific gravity of coarse aggregate prepared from brick with fly ash also studied and the results of this study suggests that 20% fly ash can be considered as the optimum fly ash content for producing good quality bricks utilizing present practiced technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bangladesh%20brick" title="Bangladesh brick">Bangladesh brick</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title=" fly ash"> fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=clay%20brick" title=" clay brick"> clay brick</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%0D%0Aproperties" title=" physical properties"> physical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a> </p> <a href="https://publications.waset.org/abstracts/41223/properties-of-fly-ash-brick-prepared-in-local-environment-of-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">254</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">680</span> Mineralogical Study of the Triassic Clay of Maaziz and the Miocene Marl of Akrach in Morocco: Analysis and Evaluating of the Two Geomaterials for the Construction of Ceramic Bricks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahar%20El%20Kasmi">Sahar El Kasmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayoub%20Aziz"> Ayoub Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Saadia%20Lharti"> Saadia Lharti</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20El%20Janati"> Mohammed El Janati</a>, <a href="https://publications.waset.org/abstracts/search?q=Boubker%20Boukili"> Boubker Boukili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nacer%20El%20Motawakil"> Nacer El Motawakil</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayom%20Chol%20Luka%20Awan"> Mayom Chol Luka Awan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two types of geomaterials (Red Triassic clay from the Maaziz region and Yellow Pliocene clay from the Akrach region) were used to create different mixtures for the fabrication of ceramic bricks. This study investigated the influence of the Pliocene clay on the overall composition and mechanical properties of the Triassic clay. The red Triassic clay, sourced from Maaziz, underwent various mechanical processes and treatments to facilitate its transformation into ceramic bricks for construction. The triassic clay was subjected to a drying chamber and a heating chamber at 100°C to remove moisture. Subsequently, the dried clay samples were processed using a Planetary Babs ll Mill to reduce particle size and improve homogeneity. The resulting clay material was sieved, and the fine particles below 100 mm were collected for further analysis. In parallel, the Miocene marl obtained from the Akrach region was fragmented into finer particles and subjected to similar drying, grinding, and sieving procedures as the triassic clay. The two clay samples are then amalgamated and homogenized in different proportions. Precise measurements were taken using a weighing balance, and mixtures of 90%, 80%, and 70% Triassic clay with 10%, 20%, and 30% yellow clay were prepared, respectively. To evaluate the impact of Pliocene marl on the composition, the prepared clay mixtures were spread evenly and treated with a water modifier to enhance plasticity. The clay was then molded using a brick-making machine, and the initial manipulation process was observed. Additional batches were prepared with incremental amounts of Pliocene marl to further investigate its effect on the fracture behavior of the clay, specifically their resistance. The molded clay bricks were subjected to compression tests to measure their strength and resistance to deformation. Additional tests, such as water absorption tests, were also conducted to assess the overall performance of the ceramic bricks fabricated from the different clay mixtures. The results were analyzed to determine the influence of the Pliocene marl on the strength and durability of the Triassic clay bricks. The results indicated that the incorporation of Pliocene clay reduced the fracture of the triassic clay, with a noticeable reduction observed at 10% addition. No fractures were observed when 20% and 30% of yellow clay are added. These findings suggested that yellow clay can enhance the mechanical properties and structural integrity of red clay-based products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=triassic%20clay" title="triassic clay">triassic clay</a>, <a href="https://publications.waset.org/abstracts/search?q=pliocene%20clay" title=" pliocene clay"> pliocene clay</a>, <a href="https://publications.waset.org/abstracts/search?q=mineralogical%20composition" title=" mineralogical composition"> mineralogical composition</a>, <a href="https://publications.waset.org/abstracts/search?q=geo-materials" title=" geo-materials"> geo-materials</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramics" title=" ceramics"> ceramics</a>, <a href="https://publications.waset.org/abstracts/search?q=akach%20region" title=" akach region"> akach region</a>, <a href="https://publications.waset.org/abstracts/search?q=maaziz%20region" title=" maaziz region"> maaziz region</a>, <a href="https://publications.waset.org/abstracts/search?q=morocco." title=" morocco."> morocco.</a> </p> <a href="https://publications.waset.org/abstracts/171399/mineralogical-study-of-the-triassic-clay-of-maaziz-and-the-miocene-marl-of-akrach-in-morocco-analysis-and-evaluating-of-the-two-geomaterials-for-the-construction-of-ceramic-bricks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171399.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">88</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">679</span> Utilization of Sludge in the Manufacturing of Fired Clay Bricks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anjali%20G.%20Pillai">Anjali G.

With growing social awareness about toxic incinerator emissions and the increasing concern over the disposal of sludge on the agricultural land, the recovery of sewage sludge as a building and construction raw material can be considered as an innovative approach to tackle the sludge disposal problem. The proposed work aims at studying the recycling ability of the sludge, generated from the water treatment process, by incorporating it into the fired clay brick units. The work involves initial study of the geotechnical characteristics of the brick-clay and the sludge. Chemical compatibility of both the materials will be analyzed by X-ray fluorescence technique. The variation in the strength aspects with varying proportions of sludge i.e. 10%, 20%, 30% and 40% in the sludge-clay mix will also be determined by the proctor density test. Based on the optimum moisture content, the sludge-clay bricks will be manufactured in a brick manufacturing plant and the modified brick units will be tested to determine the variation in compressive strength, bulk density, firing shrinkage, shrinkage loss and initial water absorption rate with respect to the conventional clay bricks. The results will be compared with the specifications given in Indian Standards to arrive at the potential use of the new bricks. The durability aspect will be studied by conducting the leachate analysis test using atomic adsorption spectrometry. The lightweight characteristics of the sludge modified bricks will be ascertained with the scanning electron microscope technique which will be indicative of the variation in pore structure with the increase in sludge content within the bricks. The work will determine the suitable proportion of the sludge – clay mix in the brick which can then be effectively implemented. The feasibility aspect of the work will be determined for commercial production of the units. The work involves providing a strategy for conversion of waste to resource. Moreover, it provides an alternative solution to the problem of growing scarcity of brick-clay for the manufacturing of fired clay bricks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eco-bricks" title="eco-bricks">eco-bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20construction%20material" title=" green construction material"> green construction material</a>, <a href="https://publications.waset.org/abstracts/search?q=sludge%20amended%20bricks" title=" sludge amended bricks"> sludge amended bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=sludge%20disposal" title=" sludge disposal"> sludge disposal</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a> </p> <a href="https://publications.waset.org/abstracts/66230/utilization-of-sludge-in-the-manufacturing-of-fired-clay-bricks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66230.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">678</span> Manufacturing Commercial Bricks with Construction and Demolition Wastes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Kara">Mustafa Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasemin%20Kilic"> Yasemin Kilic</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahattin%20Murat%20Demir"> Bahattin Murat Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%9Cmit%20Ustaoglu"> Ümit Ustaoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Cavit%20Unal"> Cavit Unal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper reports utilization of different kind of construction and demolition wastes (C&D) in the production of bricks at industrial scale. Plastered brick waste and tile wastes were collected from ISTAÇ Co. Compost and Recovery Plant, Istanbul, Turkey. Plastered brick waste and tile waste are mixed with brick clay in the proportion of 0-30% and fired at 900ºC. The physical and mechanical properties of the produced bricks were determined and evaluated according to IKIZLER Brick Company Production values, Brick Industry Association (BIA) and Turkish Standards (TS).

Some geotechnical properties (moisture content, grain size distribution) of dredged samples were also determined using the British Standard.

The dredged samples (Oroto dredged samples and Igbokoda dredged samples) have high moisture content of 90.48 % and 37.5 % respectively and both are classified as silty materials. The two dredged samples were mixed in different percentage (1- Oroto dredged sample (DS) 85 % and Igbokoda dredged sample (IS) 15 %, 2-DS 70 % and IS 30 %, 3- DS 55 % and IS 45 %, 4- DS 50 % and IS 50 %, 5- DS 45 % and IS 55 %,6- DS 30 % and IS 70 %, 7- DS 15 % and IS 85 %, 8- Clay 100 %, 9- DS 100 %, 10-IS 100 %) for the production of bricks and were tested for 7 days, 14 days, 21 days and 28 days. Although, the water absorption level of the bricks produced were high (5.635 to 33.4 %), the compressive strength on the 28th day was within the accepted British Standard. The Igbokoda dredge sample is a good material for the production of bricks when mixed with Oroto Dredged sample because the compressive strength of the material is within the accepted limit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bricks" title="bricks">bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=dredged" title=" dredged"> dredged</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture%20content" title=" moisture content"> moisture content</a>, <a href="https://publications.waset.org/abstracts/search?q=suitability" title=" suitability"> suitability</a> </p> <a href="https://publications.waset.org/abstracts/16479/investigation-of-suitability-of-dredged-wastes-for-production-of-bricks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16479.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">676</span> Olive Stone Valorization to Its Application on the Ceramic Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Mart%C3%ADn-Morales">M.

Olive oil processing generates olive stones which are dried and cleaned to remove pulp and olive stones fines to produce biofuel characterized to have high energy efficiency in combustion processes. Olive stones fine fraction is not too much appreciated as biofuel, so it is important the study of alternative solutions to be valorized. Some researchers have studied recycling different waste to produce ceramic bricks. The main objective of this study is to investigate the effects of olive stones addition on the properties of fired clay bricks for building construction. Olive stones were substituted by volume (7.5%, 15%, and 25%) to brick raw material in three different sizes (lower than 1 mm, lower than 2 mm and between 1 and 2 mm). In order to obtain comparable results, a series without olive stones was also prepared. The prepared mixtures were compacted in laboratory type extrusion under a pressure of 2.5MPa for rectangular shaped (30 mm x 60 mm x 10 mm). Dried and fired industrial conditions were applied to obtain laboratory brick samples. Mass loss after sintering, bulk density, porosity, water absorption and compressive strength of fired samples were investigated and compared with a sample manufactured without biomass. Results obtained have shown that olive stone addition decreased mechanical properties due to the increase in water absorption, although values tested satisfied the requirements in EN 772-1 about methods of test for masonry units (Part 1: Determination of compressive strength). Finally, important advantages related to the properties of bricks as well as their environmental effects could be obtained with the use of biomass studied to produce ceramic bricks. The increasing of the percentage of olive stones incorporated decreased bulk density and then increased the porosity of bricks. On the one hand, this lower density supposes a weight reduction of bricks to be transported, handled as well as the lightening of building; on the other hand, biomass in clay contributes to auto thermal combustion which involves lower fuel consumption during firing step. Consequently, the production of porous clay bricks using olive stones could reduce atmospheric emissions and improve their life cycle assessment, producing eco-friendly clay bricks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clay%20bricks" title="clay bricks">clay bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20stones" title=" olive stones"> olive stones</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=valorization" title=" valorization"> valorization</a> </p> <a href="https://publications.waset.org/abstracts/75187/olive-stone-valorization-to-its-application-on-the-ceramic-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">675</span> Evaluation of Deteriorated Fired Clay Bricks Based on Schmidt Hammer Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laurent%20Debailleux">Laurent Debailleux</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although past research has focused on parameters influencing the vulnerability of brick and its decay, in practice ancient fired clay bricks are usually replaced without any particular assessment of their characteristics. This paper presents results of non-destructive Schmidt hammer tests performed on ancient fired clay bricks sampled from historic masonry. Samples under study were manufactured between the 18th and 20th century and came from facades and interior walls. Tests were performed on three distinct brick surfaces, depending on their position within the masonry unit. Schmidt hammer tests were carried out in order to measure the mean rebound value (Rn), which refers to the resistance of the surface to successive impacts of the hammer plunger tip. Results indicate that rebound values increased with successive impacts at the same point. Therefore, mean Schmidt hammer rebound values (Rn), limited to the first impact on a surface minimises the estimation of compressive strength. In addition, the results illustrate that this technique is sensitive enough to measure weathering differences, even for different surfaces of a particular sample. Finally, the paper also highlights the relevance of considering the position of the brick within the masonry when conducting particular assessments of the material’s strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brick" title="brick">brick</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20tests" title=" non-destructive tests"> non-destructive tests</a>, <a href="https://publications.waset.org/abstracts/search?q=rebound%20number" title=" rebound number"> rebound number</a>, <a href="https://publications.waset.org/abstracts/search?q=Schmidt%20hammer" title=" Schmidt hammer"> Schmidt hammer</a>, <a href="https://publications.waset.org/abstracts/search?q=weathering%20grade" title=" weathering grade"> weathering grade</a> </p> <a href="https://publications.waset.org/abstracts/80252/evaluation-of-deteriorated-fired-clay-bricks-based-on-schmidt-hammer-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80252.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">674</span> Investigation of Cost Effective Double Layered Slab for γ-Ray Shielding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kulwinder%20Singh%20Mann">Kulwinder Singh Mann</a>, <a href="https://publications.waset.org/abstracts/search?q=Manmohan%20Singh%20Heer"> Manmohan Singh Heer</a>, <a href="https://publications.waset.org/abstracts/search?q=Asha%20Rani"> Asha Rani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The safe storage of radioactive materials has become an important issue. Nuclear engineering necessitates the safe handling of radioactive materials emitting high energy gamma-rays. Hazards involved in handling radioactive materials insist suitable shielded enclosures. With overgrowing use of nuclear energy for meeting the increasing demand of power, there is a need to investigate the shielding behavior of cost effective shielded enclosure (CESE) made from clay-bricks (CB) and fire-bricks (FB). In comparison to the lead-bricks (conventional-shielding), the CESE are the preferred choice in nuclear waste management. The objective behind the present investigation is to evaluate the double layered transmission exposure buildup factors (DLEBF) for gamma-rays for CESE in energy range 0.5-3MeV. For necessary computations of shielding parameters, using existing huge data regarding gamma-rays interaction parameters of all periodic table elements, two computer programs (GRIC-toolkit and BUF-toolkit) have been designed. It has been found that two-layered slabs show effective shielding for gamma-rays in orientation CB followed by FB than the reverse. It has been concluded that the arrangement, FB followed by CB reduces the leakage of scattered gamma-rays from the radioactive source. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buildup%20factor" title="buildup factor">buildup factor</a>, <a href="https://publications.waset.org/abstracts/search?q=clay%20bricks" title=" clay bricks"> clay bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20bricks" title=" fire bricks"> fire bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20wastage%20management" title=" nuclear wastage management"> nuclear wastage management</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20protective%20double%20layered%20slabs" title=" radiation protective double layered slabs"> radiation protective double layered slabs</a> </p> <a href="https://publications.waset.org/abstracts/43993/investigation-of-cost-effective-double-layered-slab-for-gh-ray-shielding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43993.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">407</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">673</span> Design of a CO₂-Reduced 3D Concrete Mixture Using Circular (Clay-Based) Building Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Z.%20van%20Hierden">N.

As cement is one of the major components in 3D printed concrete, achieving sustainability and carbon neutrality can be particularly challenging. To improve the sustainability of 3D printed materials, different CO₂-reducing strategies can be used, each one with a distinct level of impact and complexity. In this work, we focus on the development of these sustainable mixtures and finding alternatives. Promising alternatives for cement and clinker replacement include the use of recycled building materials, amongst which (calcined) bricks and roof tiles. To study the potential of recycled clay-based building materials, the application of calcinated clay itself is studied as well. Compared to cement, the calcination temperature of clay-based materials is significantly lower, resulting in reduced CO₂ output. Reusing these materials is therefore a promising solution for utilizing waste streams while simultaneously reducing the cement content in 3D concrete mixtures. In addition, waste streams can be locally sourced, thereby reducing the emitted CO₂ during transportation. In this research, various alternative binders are examined, such as calcined clay blends (LC3) from recycled tiles and bricks, or locally obtained clay resources. Using various experiments, a high potential for mix designs including these resources has been shown with respect to material strength, while sustaining decent printability and buildability. Therefore, the defined strategies are promising and can lead to a more sustainable, low-CO₂ mixture suitable for 3D printing while using accessible materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cement%20replacement" title="cement replacement">cement replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=3DPC" title=" 3DPC"> 3DPC</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20building%20materials" title=" circular building materials"> circular building materials</a>, <a href="https://publications.waset.org/abstracts/search?q=calcined%20clay" title=" calcined clay"> calcined clay</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20reduction" title=" CO₂ reduction"> CO₂ reduction</a> </p> <a href="https://publications.waset.org/abstracts/162171/design-of-a-co2-reduced-3d-concrete-mixture-using-circular-clay-based-building-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162171.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">672</span> Experimental Study on the Variation of Young's Modulus of Hollow Clay Brick Obtained from Static and Dynamic Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Aboudalle">M.

Being used in structural applications, predicting the performance of clay brick masonry allows a significant cost reduction, in terms of practical experimentation. The behavior of masonry walls depends on the behavior of their elementary components, such as bricks, joints, and coatings. Therefore, it is necessary to consider it at different scales (from the scale of the intrinsic material to the real scale of the wall) and then to develop appropriate models, using numerical simulations. The work presented in this paper focuses on the mechanical characterization of the terracotta material at ambient temperature. As a result, the static Young’s modulus obtained from the flexural test shows different values in comparison with the compression test, as well as with the dynamic Young’s modulus obtained from the Impulse excitation of vibration test. Moreover, the Young's modulus varies according to the direction in which samples are extracted, where the values in the extrusion direction diverge from the ones in the orthogonal directions. Based on these results, hollow bricks can be considered as transversely isotropic bimodulus material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bimodulus%20material" title="bimodulus material">bimodulus material</a>, <a href="https://publications.waset.org/abstracts/search?q=hollow%20clay%20brick" title=" hollow clay brick"> hollow clay brick</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%B1mpulse%20excitation%20of%20vibration" title=" ımpulse excitation of vibration"> ımpulse excitation of vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=transversely%20isotropic%20material" title=" transversely isotropic material"> transversely isotropic material</a>, <a href="https://publications.waset.org/abstracts/search?q=young%E2%80%99s%20modulus" title=" young’s modulus"> young’s modulus</a> </p> <a href="https://publications.waset.org/abstracts/131058/experimental-study-on-the-variation-of-youngs-modulus-of-hollow-clay-brick-obtained-from-static-and-dynamic-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131058.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">197</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">671</span> Assessing the Suitability of South African Waste Foundry Sand as an Additive in Clay Masonry Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nthabiseng%20Portia%20Mahumapelo">Nthabiseng Portia Mahumapelo</a>, <a href="https://publications.waset.org/abstracts/search?q=Andre%20van%20Niekerk"> Andre van Niekerk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ndabenhle%20Sosibo"> Ndabenhle Sosibo</a>, <a href="https://publications.waset.org/abstracts/search?q=Nirdesh%20Singh"> Nirdesh Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The foundry industry generates large quantities of solid waste in the form of waste foundry sand. The ever-increasing quantities of this type of industrial waste put pressure on land-filling space and its proper management has become a global concern. The South African foundry industry is not different when it comes to this solid waste generation. Utilizing the foundry waste sand in other applications has become an attractive avenue to deal with this waste stream. In the present paper, an evaluation was done on the suitability of foundry waste sand as an additive in clay masonry products. Purchased clay was added to the foundry waste sand sample in a 50/50 ratio. The mixture was named FC sample. The FC sample was mixed with water in a pan mixer until the mixture was consistent and suitable for extrusion. The FC sample was extruded and cut into briquettes. Water absorption, shrinkage and modulus of rupture tests were conducted on the resultant briquettes. Foundry waste sand and FC samples were respectively characterized mineralogically using X-Ray Diffraction, and the major and trace elements were determined using Inductively Coupled Plasma Optical Emission Spectroscopy. Adding purchased clay to the foundry waste sand positively influenced the workability of the test sample. Another positive characteristic was the low linear shrinkage, which indicated that products manufactured from the FC sample would not be susceptible to cracking. The water absorption values were acceptable and the unfired and fired strength values of the briquette’s samples were acceptable. In conclusion, tests showed that foundry waste sand can be used as an additive in masonry clay bricks, provided it is blended with good quality clay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foundry%20waste%20sand" title="foundry waste sand">foundry waste sand</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry%20clay%20bricks" title=" masonry clay bricks"> masonry clay bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20rupture" title=" modulus of rupture"> modulus of rupture</a>, <a href="https://publications.waset.org/abstracts/search?q=shrinkage" title=" shrinkage"> shrinkage</a> </p> <a href="https://publications.waset.org/abstracts/105027/assessing-the-suitability-of-south-african-waste-foundry-sand-as-an-additive-in-clay-masonry-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105027.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">230</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">670</span> Effects of Aggregate Type and Concrete Age on Compressive Strength After Subjected to Elevated Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20M.%20Seyam">Ahmed M.

The specimens were cured in water for seven days, then kept in the laboratory for 120 days and 240 days. The concrete specimens were heated in an electric furnace up to 200, 400, 600, 800, and 1000 °C and kept at these temperatures for two hours heating, then for 24 hours cooling. The residual compressive strength of the specimens was measured. The results showed that, the elevated temperature induces a significant decrease in a compressive strength in both normal weight and lightweight aggregate concrete, by comparing the behavior of different mixes, in all cases, the strength of the specimens containing crushed andesite aggregates showed a better performance for compressive strength after exposure to elevated temperatures over 800 °C, while the specimens containing expanded glass showing the least residual strength after subjected to elevated temperature; moreover the age of the concrete in all mixes has also been an effective factor, the behavior of the concrete strength loss by increasing heating temperature was not changed but the strength results showing the better performance and higher compressive strength in both ambient and elevated temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elevated%20temperature" title="elevated temperature">elevated temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20age" title=" concrete age"> concrete age</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=expanded%20clay" title=" expanded clay"> expanded clay</a>, <a href="https://publications.waset.org/abstracts/search?q=expanded%20glass" title=" expanded glass"> expanded glass</a>, <a href="https://publications.waset.org/abstracts/search?q=crushed%20andesite" title=" crushed andesite"> crushed andesite</a>, <a href="https://publications.waset.org/abstracts/search?q=crushed%20clay%20bricks" title=" crushed clay bricks"> crushed clay bricks</a> </p> <a href="https://publications.waset.org/abstracts/151228/effects-of-aggregate-type-and-concrete-age-on-compressive-strength-after-subjected-to-elevated-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151228.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">118</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">669</span> Effect of Clay Brick Filler on Properties of Self-Compacting Lightweight Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Juradin">Sandra Juradin</a>, <a href="https://publications.waset.org/abstracts/search?q=Lidia%20Karla%20Vranjes"> Lidia Karla Vranjes </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The environmental impact of the components of concrete is considerable. The paper presents the influence of ground clay brick filler on the properties of self-compacting lightweight concrete (SCLC). In the manufacture and transport of clay bricks, product damage may occur. The filler was obtained by milling the damaged clay brick and sieved under the 0.04 mm size. The composition of each of SCLC mixture was determined according to the CBI method and compared with EFNARC (European Association) criteria. Self-compacting lightweight concrete has been tested in a fresh (slump flow method, visual assessment of stability, T50 time, V-funnel method, L-box method and J-ring) and hardened state (compressive strengths and dynamic modulus of elasticity). Mixtures with this filler had good results of compressive strength, but in fresh state the mixtures were sticky. All results were analyzed and compared with previous studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CBI%20methods" title="CBI methods">CBI methods</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20clay%20brick" title=" ground clay brick"> ground clay brick</a>, <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20lightweight%20concrete" title=" self-compacting lightweight concrete"> self-compacting lightweight concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20fume" title=" silica fume"> silica fume</a> </p> <a href="https://publications.waset.org/abstracts/85392/effect-of-clay-brick-filler-on-properties-of-self-compacting-lightweight-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85392.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">668</span> Properties of Compressed Earth Blocks Enhanced with Clay Pozzolana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Humphrey%20Danso">Humphrey Danso</a>, <a href="https://publications.waset.org/abstracts/search?q=Seth%20Adu"> Seth Adu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The high cost of cement and its greenhouse effect on the environment have led to the use of alternative building materials in the production of block and bricks. This study seeks to investigate the properties of compressed earth blocks (CEBs) enhanced with clay pozzolana. CEBs of size 290 × 140 × 100 mm were prepared with 10, 20 and 30 % weight of clay pozzolana. The CEBs were compressed at a constant pressure of 5 MPa and cured for 28 days. The blocks, after 7, 14, 21 and 28 days of curing were tested for density, water absorption, compressive strength and erosion. It was found that amount of pozzolana content did not have much influence on blocks’ density. There was a decline in water absorption of the stabilised blocks ranged between 32.8% and 252.2% over the unstabilised blocks. The highest compressive strength (3.75MPa) of the stabilized blocks was achieved at 28th day of curing with 30% clay pozzolana content, which showed an improvement of 116.8% strength over the unstabilised blocks. Furthermore, there was a statistically significant difference in the erosion resistance between the stabilized blocks and the unstabilised blocks. The study concludes that the inclusion of the clay pozzolana increased the properties of the CEBs, and therefore recommended for use in the building of houses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clay%20pozzolana" title="clay pozzolana">clay pozzolana</a>, <a href="https://publications.waset.org/abstracts/search?q=compressed%20earth%20blocks%20%28CEBs%29" title=" compressed earth blocks (CEBs)"> compressed earth blocks (CEBs)</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion%20test" title=" erosion test "> erosion test </a> </p> <a href="https://publications.waset.org/abstracts/87347/properties-of-compressed-earth-blocks-enhanced-with-clay-pozzolana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87347.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">667</span> LEGO Bricks and Creativity: A Comparison between Classic and Single Sets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maheen%20Zia">Maheen Zia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Near the early twenty-first century, LEGO decided to diversify its product range which resulted in more specific and single-outcome sets occupying the store shelves than classic kits having fairly all-purpose bricks. Earlier, LEGOs came with more bricks and lesser instructions. Today, there are more single kits being produced and sold, which come with a strictly defined set of guidelines. If one set is used to make a car, the same bricks cannot be put together to produce any other article. Earlier, multiple bricks gave children a chance to be imaginative, think of new items and construct them (by just putting the same pieces differently). The new products are less open-ended and offer a limited possibility for players in both designing and realizing those designs. The article reviews (in the light of existing research) how classic LEGO sets could help enhance a child’s creativity in comparison with single sets, which allow a player to interact (not experiment) with the bricks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructive%20play" title="constructive play">constructive play</a>, <a href="https://publications.waset.org/abstracts/search?q=creativity" title=" creativity"> creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=LEGO" title=" LEGO"> LEGO</a>, <a href="https://publications.waset.org/abstracts/search?q=play-based%20learning" title=" play-based learning"> play-based learning</a> </p> <a href="https://publications.waset.org/abstracts/130650/lego-bricks-and-creativity-a-comparison-between-classic-and-single-sets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130650.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">666</span> Development of Light-Weight Refractory Bricks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liaqat%20Ali">Liaqat Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Furqan%20Ahmad"> Furqan Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The heat losses should be controlled during the high temperature processes from energy conservation point of view.

The preparation of mixtures is achieved with 04 types of different masse compositions, consisting of gray and yellow clay, and coal.

Initially, each natural moisture content of a raw material has been determined at the temperature of 105°C in a laboratory oven. The Influence of low-coal content on absorption, the apparent density, the contraction and the resistance during compression have been evaluated. The experimental results showed that the optimized composition could be obtained by adding 10% by weight of coal leading thus to insulating ceramic products with water absorption, a density and resistance to compression of 9.40 %, 1.88 g/cm3, 35.46 MPa, respectively.

In Bangladesh, stones cannot be used as coarse aggregate in infrastructure works as they are not available and need to be imported from abroad. As a result, bricks are mostly used as coarse aggregates in concrete as they are cheaper and easily produced here. Clay is the raw material for producing brick. Due to rapid urban growth and the industrial revolution, demand for brick is increasing, which led to a decrease in the topsoil. This study aims to produce lightweight block aggregates with sufficient strength utilizing RHA at low cost and use them as an ingredient of concrete. RHA, because of its pozzolanic behavior, can be utilized to produce better quality block aggregates at lower cost, replacing clay content in the bricks. The whole study can be divided into three parts. In the first part, characterization tests on RHA and clay were performed to determine their properties. Six different types of RHA from different mills were characterized by XRD and SEM analysis. Their fineness was determined by conducting a fineness test. The result of XRD confirmed the amorphous state of RHA. The characterization test for clay identifies the sample as “silty clay” with a specific gravity of 2.59 and 14% optimum moisture content. In the second part, blocks were produced with six different types of RHA with different combinations by volume with clay. Then mixtures were manually compacted in molds before subjecting them to oven drying at 120 °C for 7 days. After that, dried blocks were placed in a furnace at 1200 °C to produce ultimate blocks. Loss on ignition test, apparent density test, crushing strength test, efflorescence test, and absorption test were conducted on the blocks to compare their performance with the bricks. For 40% of RHA, the crushing strength result was found 60 MPa, where crushing strength for brick was observed 48.1 MPa. In the third part, the crushed blocks were used as coarse aggregate in concrete cylinders and compared them with brick concrete cylinders. Specimens were cured for 7 days and 28 days. The highest compressive strength of block cylinders for 7 days curing was calculated as 26.1 MPa, whereas, for 28 days curing, it was found 34 MPa. On the other hand, for brick cylinders, the value of compressing strength of 7 days and 28 days curing was observed as 20 MPa and 30 MPa, respectively. These research findings can help with the increasing demand for topsoil of the earth, and also turn a waste product into a valuable one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characterization" title="characterization">characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=furnace" title=" furnace"> furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=pozzolanic%20behavior" title=" pozzolanic behavior"> pozzolanic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20husk%20ash" title=" rice husk ash"> rice husk ash</a> </p> <a href="https://publications.waset.org/abstracts/132122/utilization-of-rice-husk-ash-with-clay-to-produce-lightweight-coarse-aggregates-for-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132122.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">663</span> Availability of Metals in Fired Bricks Incorporating Harbour Sediments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabienne%20Baraud">Fabienne Baraud</a>, <a href="https://publications.waset.org/abstracts/search?q=Lydia%20Leleyter"> Lydia Leleyter</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Poree"> Sandra Poree</a>, <a href="https://publications.waset.org/abstracts/search?q=Melanie%20Lemoine"> Melanie Lemoine</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatiha%20Oudghiri"> Fatiha Oudghiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alternative solutions to immersion at sea are searched for the huge amounts of dredged sediments around the world that might contain various types of contaminants. Possible re-uses of such materials in civil engineering appear as sustainable solutions. The French SEDIBRIC project (valorisation de SEDIments en BRIQues et tuiles) aims to replace a part of natural clays with dredged sediments in the preparation of fired bricks. The potential environmental impact of this re-use is explored to complete the technical and economic feasibility of the study. As part of the project, we investigate the environmental availability of metallic elements (Al, Ca, Cd, Co, Cr, Cu, Fe, Ni, Mg, Mn, Pb, Ti, and Zn) initially present in the dredged sediments selected for the project. Leaching tests (with H₂O, HCl, or EDTA) are conducted in the sediments than in the final bricks in order to evaluate the possible influence of some steps of the bricks manufacturing (desalination pre-treatment, firing, etc.). The desalination pre-treatment using tap water has no or few impacts on the environmental availability of the studied elements. On the opposite, the firing process (900°C) affects the value of the total content of elements detected in the bricks but also the environmental availability for various elements. For instance, Cd, Cu, Pb, and Zn are stabilized in the bricks, whereas the availability of some other elements (i.e., Cr, Ni) increases, depending on the nature of the extracting solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=availability" title="availability">availability</a>, <a href="https://publications.waset.org/abstracts/search?q=bricks" title=" bricks"> bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=dredged%20sediments" title=" dredged sediments"> dredged sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=metals" title=" metals"> metals</a> </p> <a href="https://publications.waset.org/abstracts/129774/availability-of-metals-in-fired-bricks-incorporating-harbour-sediments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129774.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">662</span> New Approach to Encapsulated Clay/Wax Nanocomposites Inside Polystyrene Particles via Minemulstion Polymerization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nagi%20Greesh">Nagi Greesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study highlights a new method to obtain multiphase composites particles containing hydrophobic (wax) and inorganic (clay) compounds.

Ancient Egyptians utilized various methods to prevent wind damage to their ancient architecture throughout the ancient Egyptian periods . One of the techniques employed by ancient Egyptians was the use of clay or compacted earth as a filling material between opposing walls made of stone, bricks, or mud bricks. The walls made of reeds or woven tree branches were covered with clay to prevent the infiltration of winds and rain, enhancing structural integrity, this method was commonly used in hollow layers . Additionally, Egyptian engineers innovated a type of adobe brick with uniformly leveled sides, manufactured from dried clay. They utilized stone barriers, constructed wind traps, and planted trees in rows parallel to the prevailing wind direction. Moreover, they employed receptacles to drain rainwater resulting from wind-loaded rain and used mortar to fill gaps in roofs and structures.

Compressive strength test was carried out on the dried samples using a Testometric Universal Testing Machine (TUTM) equipped with a computer and printer, optimum compression of 4.41 kN/mm2 was obtained at 12.5 % sodium silicate; the experimental results were modeled with MATLAB and Origin packages using polynomial regression equations that predicted the estimated values for dry compressive strength and later validated with Pearson’s rank correlation coefficient, thereby obtaining a very high positive correlation value of 0.97. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dry%20compressive%20strength" title="dry compressive strength">dry compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=kaolin" title=" kaolin"> kaolin</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20silicate" title=" sodium silicate"> sodium silicate</a> </p> <a href="https://publications.waset.org/abstracts/26382/evaluation-of-the-dry-compressive-strength-of-refractory-bricks-developed-from-local-kaolin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26382.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">455</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">658</span> Use of Chemical Extractions to Estimate the Metals Availability in Bricks Made of Dredged Sediments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabienne%20Baraud">Fabienne Baraud</a>, <a href="https://publications.waset.org/abstracts/search?q=Lydia%20Leleyter"> Lydia Leleyter</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Poree"> Sandra Poree</a>, <a href="https://publications.waset.org/abstracts/search?q=Melanie%20Lemoine"> Melanie Lemoine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> SEDIBRIC (valorization de SEDIments en BRIQues et tuiles) is a French project that aims to replace a part of natural clays with dredged sediments in the preparation of fired bricks in order to propose an alternative solution for the management of harbor dredged sediments. The feasibility of such re-use is explored from a technical, economic, and environmental point of view. The present study focuses on the potential environmental impact of various chemical elements (Al, Ca, Cd, Co, Cr, Cu, Fe, Ni, Mg, Mn, Pb, Ti, and Zn) that are initially present in the dredged sediments. The total content (after acid digestion) and the environmental availability (estimated by single extractions with various extractants) of these elements are determined in the raw sediments and in the obtained fired bricks. The possible influence of some steps of the manufacturing process (sediment pre-treatment, firing) is also explored. The first results show that the pre-treatment step, which uses tap water to desalinate the raw sediment, does not influence the environmental availability of the studied elements. However, the firing process, performed at 900°C, can affect the amount of some elements detected in the bricks, as well as their environmental availability. We note that for Cr, or Ni, the HCl or EDTA availability was increased in the brick (compared to the availability in the raw sediment). For Cd, Cu, Pb, and Zn, the HCl and EDTA availability was reduced in the bricks, meaning that these elements were stabilized within the bricks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bricks" title="bricks">bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20extraction" title=" chemical extraction"> chemical extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=metals" title=" metals"> metals</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a> </p> <a href="https://publications.waset.org/abstracts/132584/use-of-chemical-extractions-to-estimate-the-metals-availability-in-bricks-made-of-dredged-sediments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132584.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">657</span> Use of Industrial Wastes for Production of Low-Cost Building Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frank%20Aneke">Frank Aneke</a>, <a href="https://publications.waset.org/abstracts/search?q=Elizabeth%20Theron"> Elizabeth Theron</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Demand for building materials in the last decade due to growing population, has caused scarcity of low-cost housing in South Africa.

Manoppo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ordinary Portland Cement (OPC) takes a big role as a concrete binder in infrastructure construction purposes, nevertheless, it produces CO2 emissions abundantly. To reduce the CO2 emissions produced by OPC concrete, nowadays, geopolymer material become one of the solutions due to it being a binder made from waste with pozzolan material. In concrete industries, geopolymer concrete has evolved as a more environmentally friendly material than OPC concrete. The geopolymer concrete was created without the usage of OPC known as cementless concrete materials. Geopolymer concrete obtains silicon and aluminum from industrial by-products such as fly ash, ground granulated blast furnace slag, and kaolinite. A highly alkaline solution chemically activates Si and Al, forming a matrix that holds together the loose aggregates as well as additional unreacted components in the mixture. They are then dissolved in alkaline activating solutions, where they polymerize into molecular chains, resulting in rigid binders. This research aims to get an eco-friendly material that can reduce the use of OPC as a binder and be used for infrastructure development end-products such as Curbs, Pavement Bricks, and Wall Bricks. This research was conducted as applied research to develop new products of environmentally friendly materials by utilizing fly ash and employed for infrastructure development, particularly for the production of end products such as Curbs, Pavement Bricks, and Wall Bricks. Three types of end products with various dimensions and mix designs have been made and tested in the laboratory, resulting in quantitative datasets to be used for identifying patterns and relationships among density, compressive strength, flexural strength, and water absorption. The result found that geopolymer binders can be used for the production of curbs, pavement bricks, and wall bricks. Geopolymer curbs have an average compressive strength of 19,36 MPa, which can be determined as K-233 concrete. Geopolymer pavement bricks have an average compressive strength of 20,79 MPa. It can be used in parking areas and determined as the grade B of pavement bricks according to SNI 03-0691-1996. Geopolymer wall bricks have an average compressive strength of 11,24 MPa, which can be determined as the grade I of Wall Bricks according to SNI 03-0349-1989. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorption" title="absorption">absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=curbs" title=" curbs"> curbs</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20products" title=" end products"> end products</a>, <a href="https://publications.waset.org/abstracts/search?q=geopolymer" title=" geopolymer"> geopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement%20bricks" title=" pavement bricks"> pavement bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=wall%20bricks" title=" wall bricks"> wall bricks</a> </p> <a href="https://publications.waset.org/abstracts/190194/fly-ash-based-geopolymer-concrete-as-curbs-pavement-bricks-and-wall-bricks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190194.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">31</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">655</span> Effects of Crushed Waste Aggregate from the Manufacture of Clay Bricks on Rendering Cement Mortar Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benmalek%20M.%20Larbi">Benmalek M.

The brick, in crushed form, was from a local brick manufacturer that was rejected due to being of-standard. It was used to replace 33.33 %, 50 %, 66.66 % and 100 % by weight of the quarry sand in mortar. Effects of the brick replacement on the mortar key properties intended for wall plastering were investigated; these are workability, compressive strength, flexural strength, linear shrinkage, water absorption by total immersion and by capillary suction. The results showed that as the brick replacement level increased, the mortar workability reduced. The linear shrinkage increases over time and decreases with the introduction of brick waste. The compressive and flexural strengths decrease with the increase of brick waste because of their great water absorption. <p class="card-text"><strong>Keywords:</strong> <a
