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">2214</span> An Approach to Make Low-Cost Self-Compacting Geo-Polymer Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankit%20Chakraborty">Ankit Chakraborty</a>, <a href="https://publications.waset.org/abstracts/search?q=Raj%20Shah"> Raj Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Prayas%20Variya"> Prayas Variya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self-compacting geo-polymer concrete is a blended version of self-compacting concrete developed in Japan by Okamura.

This method is eco-friendly as there is low CO₂ emission and reduces labor cost due to its self-compacting property and zero percent cement content. We are making an approach to reduce concreting cost and make concreting eco-friendly by replacing cement fully and sand by a certain amount of industrial waste. It will reduce overall concreting cost due to its self-compatibility and replacement of materials, forms eco-friendly concreting technique and gives better fresh property and hardened property results compared to self-compacting concrete and geo-polymer concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geopolymer%20concrete" title="geopolymer concrete">geopolymer concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20cost%20concreting" title=" low cost concreting"> low cost concreting</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20carbon%20emission" title=" low carbon emission"> low carbon emission</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20compactability" title=" self compactability"> self compactability</a> </p> <a href="https://publications.waset.org/abstracts/77540/an-approach-to-make-low-cost-self-compacting-geo-polymer-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77540.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">232</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">2213</span> Properties of Self-Compacting Concrete Mixed with Fly Ash</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abhinandan%20Singh%20Gill">Abhinandan Singh Gill</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurbir%20Kaur%20Jawanda"> Gurbir Kaur Jawanda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since the introduction of self-consolidating concrete (SCC) in Japan during the late 1980’s, acceptance and usage of this concrete in the construction industry has been steadily gaining momentum. In the United States, the usage of SCC has been spearheaded by the precast concrete industry. Good SCC must possess the following key fresh properties: filling ability, passing ability, and resistance to segregation. Self-compacting concrete is one of 'the most revolutionary developments' in concrete research; this concrete is able to flow and to fill the most restocked places of the form work without vibration. There are several methods for testing its properties. In the fresh state: the most frequently used are slump flow test, L box and V-funnel. This work presents properties of self-compacting concrete, mixed with fly ash. The test results for acceptance characteristics of self-compacting concrete such as slump flow; V-funnel and L-Box are presented. Further, the compressive strength at the ages of 7, 28 days was also determined and results are included here. <p class="card-text"><strong>Keywords:</strong> <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=fly%20ash" title=" fly ash"> fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20concrete" title=" self-compacting concrete"> self-compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=slump%20flow%20test" title=" slump flow test"> slump flow test</a>, <a href="https://publications.waset.org/abstracts/search?q=super%20plasticizer" title=" super plasticizer"> super plasticizer</a> </p> <a href="https://publications.waset.org/abstracts/24964/properties-of-self-compacting-concrete-mixed-with-fly-ash" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24964.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">411</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">2212</span> Effect of Manual Compacting and Semi-Automatic Compacting on Behavior of Stabilized Earth Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sihem%20Chaibeddra">Sihem Chaibeddra</a>, <a href="https://publications.waset.org/abstracts/search?q=Fattoum%20Kharchi"> Fattoum Kharchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahim%20Kahlouche"> Fahim Kahlouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Youcef%20Benna"> Youcef Benna </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the recent years, a considerable level of interest has been developed on the use of earth in construction, led by its rediscovery as an environmentally building material. The Stabilized Earth Concrete (SEC) is a good alternative to the cement concrete, thanks to its thermal and moisture regulating features. Many parameters affect the behavior of stabilized earth concrete. This article presents research results related to the influence of the compacting nature on some SEC properties namely: The mechanical behavior, capillary absorption, shrinkage and sustainability to water erosion, and this, basing on two types of compacting: Manual and semi-automatic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=behavior" title="behavior">behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=compacting" title=" compacting"> compacting</a>, <a href="https://publications.waset.org/abstracts/search?q=manual" title=" manual"> manual</a>, <a href="https://publications.waset.org/abstracts/search?q=SEC" title=" SEC"> SEC</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-automatic" title=" semi-automatic"> semi-automatic</a> </p> <a href="https://publications.waset.org/abstracts/45931/effect-of-manual-compacting-and-semi-automatic-compacting-on-behavior-of-stabilized-earth-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45931.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">361</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">2211</span> Eco-Efficient Self-Compacting Concrete for Sustainable Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valeria%20Corinaldesi">Valeria Corinaldesi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In general, for self-compacting concrete production, a high volume of very fine materials is necessary in order to make the concrete more fluid and cohesive. For this purpose, either rubble powder (which is a powder obtained from suitable treatment of rubble from building demolition) or ash from municipal solid waste incineration was used as mineral addition in order to ensure adequate rheological properties of the self-compacting concrete in the absence of any viscosity modifying admixture. Recycled instead of natural aggregates were used by completely substituting the coarse aggregate fraction. The fresh concrete properties were evaluated through the slump flow, the V-funnel and the L-box test. Compressive strength and segregation resistance were also determined. The results obtained showed that self-compacting concrete could be successfully developed by incorporating both recycled aggregates and waste powders with an improved quality of the concrete surface finishing.

This large amount of seeds led to studies into the possible use as aggregates in lightweight concrete for some special structures. The utilization of DPS as aggregate in concrete provides a good solution as alternative aggregate to the stone aggregate. It has been recognized that, DPS can be used as coarse aggregate in structural lightweight concrete industry. For any structure member, the durability is one of the most important considerations during its service life. This paper presents the durability properties of DPS concrete. These include the water permeability, water absorption, sorptivity and chloride penetration.

It has a wide area of use from production of carious ornaments to chemical industry. It has a white and irregular crystalline structure. It is wet and moist when extracted, which is a good form for processing. At drying phase, it gradually loses its moisture and becomes lighter and harder. In through-dry state, meerschaum is durable and floats on the water. After processing of meerschaum, A ratio between %15 to %40 of the amount becomes waste. This waste is usually kept in a dry-atmosphere which is isolated from environmental effects so that to be used right away when needed. In this study, use of meerschaum waste as aggregate in lightweight concrete is studied. Stress-strain diagrams for concrete with meerschaum aggregate are obtained. Then, stress-strain diagrams of lightweight concrete and concrete with regular aggregate are compared. It is concluded that meerschaum waste can be used in production of lightweight concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lightweight%20concrete" title="lightweight concrete">lightweight concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=meerschaum" title=" meerschaum"> meerschaum</a>, <a href="https://publications.waset.org/abstracts/search?q=aggregate" title=" aggregate"> aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=sepiolite" title=" sepiolite"> sepiolite</a>, <a href="https://publications.waset.org/abstracts/search?q=stress-strain%20diagram" title=" stress-strain diagram"> stress-strain diagram</a> </p> <a href="https://publications.waset.org/abstracts/18253/making-lightweight-concrete-with-meerschaum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18253.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">604</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">2206</span> A Study on the Influence of Internal Sulfate on the Properties of Self-Compacting Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abbas%20S.%20Al-Ameeri%20Rawaa%20H.%20Issa">Abbas S.

Sulfate drastically influences the properties of concrete. This experimental study is aimed at investigating the effect of internal sulfates on fresh and some of the hardened properties of self compacting concrete (SCC) made from locally available materials. Tests were conducted on five mixes, with five SO3 levels (3.9, 5, 6, 7 and 8) (% by wt. of cement). The last four SO3 levels are outside the limits of the Iraqi specifications (IQS NO.45/1984). The results indicated that sulfate passively influenced the fresh properties such as decreased workability, and effect on hardened properties of the self compacting concrete. Also, the result indicated the optimum SO3 content which gives maximum strength and little tendency to expanding, which showed up at a content equal to 5% (by wt of cement), is more than acceptable limits of Iraqi specifications. Further increase in sulfates content in concrete after this optimum value showed a considerable reduction in mechanical properties of self-compacting concrete, and increment in expansion of concrete. The percentages of reduction in compressive strength, splitting tensile strength, flexural strength, static modulus of elasticity and ultrasonic pulse velocity at their later age were ranged between 10.89-36.14%, 12.90-33.33%, 7.98-36.35%, 16.36 -38.37% and 1.03-10.88% respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20concrete" title="self-compacting concrete">self-compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfate%20attack" title=" sulfate attack"> sulfate attack</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20sulfate%20attack" title=" internal sulfate attack"> internal sulfate attack</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20properties" title=" fresh properties"> fresh properties</a>, <a href="https://publications.waset.org/abstracts/search?q=harden%20properties" title=" harden properties"> harden properties</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20SO3%20content" title=" optimum SO3 content "> optimum SO3 content </a> </p> <a href="https://publications.waset.org/abstracts/11393/a-study-on-the-influence-of-internal-sulfate-on-the-properties-of-self-compacting-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11393.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">270</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">2205</span> The Influence of Zeolitic Spent Refinery Admixture on the Rheological and Technological Properties of Steel Fiber Reinforced Self- Compacting Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C5%BDymantas%20Rud%C5%BEionis">Žymantas Rudžionis</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulius%20Grigali%C5%ABnas"> Paulius Grigaliūnas</a>, <a href="https://publications.waset.org/abstracts/search?q=Danut%C4%97%20Vai%C4%8Diukynien%C4%97"> Danutė Vaičiukynienė</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By planning this experimental work to investigate the effect of zeolitic waste on rheological and technological properties of self-compacting fiber reinforced concrete, we had an intention to draw attention to the environmental factor.

In the study, both SCC and CC were produced in three different concrete classes (C25, C50 and C70) and the other parameter (i.e curing condition) was determined as two levels: moisture and air curing. It was observed that, for both curing environments and all strength classes of concrete, SCCs had lower capillary water absorption values than that of CCs. It was also detected that, for both SCC and CC, capillary water absorption values of samples kept in moisture curing were significantly lower than that of samples stored in air curing.

Tazky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current trends in the building industry are oriented towards the reduction of maintenance costs and the ecological benefits of buildings or building materials. Surface treatment of building materials with photocatalytic active titanium dioxide added into concrete can offer a good solution in this context. Architectural concrete has one disadvantage &ndash; dust and fouling keep settling on its surface, diminishing its aesthetic value and increasing maintenance e costs. Concrete surface &ndash; silicate material with open porosity &ndash; fulfils the conditions of effective photocatalysis, in particular, the self-cleaning properties of surfaces. This modern material is advantageous in particular for direct finishing and architectural concrete applications. If photoactive titanium dioxide is part of the top layers of road concrete on busy roads and the facades of the buildings surrounding these roads, exhaust fumes can be degraded with the aid of sunshine; hence, environmental load will decrease. It is clear that options for removing pollutants like nitrogen oxides (NOx) must be found. Not only do these gases present a health risk, they also cause the degradation of the surfaces of concrete structures. The photocatalytic properties of titanium dioxide can in the long term contribute to the enhanced appearance of surface layers and eliminate harmful pollutants dispersed in the air, and facilitate the conversion of pollutants into less toxic forms (e.g., NOx to HNO<sub>3</sub>). This paper describes verification of the photocatalytic properties of titanium dioxide and presents the results of mechanical and physical tests on samples of architectural lightweight self-compacting concretes (LWSCC). The very essence of the use of LWSCC is their rheological ability to seep into otherwise extremely hard accessible or inaccessible construction areas, or sections thereof where concrete compacting will be a problem, or where vibration is completely excluded. They are also able to create a solid monolithic element with a large variety of shapes; the concrete will at the same meet the requirements of both chemical aggression and the influences of the surrounding environment. Due to their viscosity, LWSCCs are able to imprint the formwork elements into their structure and thus create high quality lightweight architectural concretes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photocatalytic%20concretes" title="photocatalytic concretes">photocatalytic concretes</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20dioxide" title=" titanium dioxide"> titanium dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20concretes" title=" architectural concretes"> architectural concretes</a>, <a href="https://publications.waset.org/abstracts/search?q=Lightweight%20Self-Compacting%20Concretes%20%28LWSCC%29" title=" Lightweight Self-Compacting Concretes (LWSCC)"> Lightweight Self-Compacting Concretes (LWSCC)</a> </p> <a href="https://publications.waset.org/abstracts/72991/photocatalytic-active-surface-of-lwscc-architectural-concretes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72991.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">295</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">2202</span> Enhancing Value of Dam Dredged Sediments as a Component of a Self Compacting Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Belas">N.

These sediments have to be subjected to thermal treatment to become reactive with the cement and thus to obtain an artificial pozzolana. It is therefore a question of developing the calcined mud as substitutable material in part to the cement used in the composition of self compacting concrete. The objective of the present work is to highlight its influence on the behavior of self compacting concrete compared to that of the natural pozzolana and this, in fresh and hardened states. The study is being conducted on three SCC, the first using 20% in volume of natural pozzolana, the second with 20 % of calcined mud and the third for the sake of comparison is made with cement only. The first results showed the possibility of obtaining SCC with calcined mud complying with the AFGC recommendations having a good mechanical behavior which makes interesting its development as construction materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dam" title="dam">dam</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20state" title=" fresh state"> fresh state</a>, <a href="https://publications.waset.org/abstracts/search?q=hardened%20state%20mud" title=" hardened state mud"> hardened state mud</a>, <a href="https://publications.waset.org/abstracts/search?q=sediments" title=" sediments"> sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20compacting%20concrete" title=" self compacting concrete"> self compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=valorization" title=" valorization "> valorization </a> </p> <a href="https://publications.waset.org/abstracts/19053/enhancing-value-of-dam-dredged-sediments-as-a-component-of-a-self-compacting-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19053.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">515</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">2201</span> Predicting Durability of Self Compacting Concrete Using Artificial Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Boudjelthia">R.

Such concrete requires a high slump which can be achieved by the addition of superplasticizers to the concrete mix. In the present work, bagasse ash is utilised as a replacement of cement in self-compacting concrete. This serves the purpose of both land disposal and environmental concerns related to the disposal of bagasse ash. Further, an experimental program was carried out to study the fresh, strength, and durability properties of self-compacting concrete made with bagasse ash. The mixes were prepared with four percentages (0, 5, 10 and 15) of bagasse ash as partial replacement of cement. Properties investigated were; Slump-flow, V-funnel and L-box, Compressive strength, Splitting tensile strength, Chloride-ion penetration resistance and Water absorption. Compressive and splitting tensile strength tests were conducted at the age of 7 and 28 days. Rapid chloride-ion permeability test was carried at the age of 28 days and water absorption test was carried out at the age of 7 days after initial curing of 28 days. Test results showed that there is an increase in the compressive strength and splitting tensile strength of the concrete specimens having up to 10% replacement level, however, there is a slight decrease at 15% level of replacement. Resistance to chloride-ion penetration of the specimens increased as the percentage of replacement was increased. The charge passed in all the specimens containing bagasse ash was lower than that of the specimen without bagasse ash. Water absorption of the specimens decreased up to 10% replacement level and increased at 15% level of replacement. Hence, it can be concluded that optimum level of replacement of cement with bagasse ash in self-compacting concrete comes out to be 10%; at which the self-compacting concrete has satisfactory flow characteristics (as per the European guidelines), improved compressive and splitting tensile strength and better durability properties as compared to the control mix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bagasse%20ash" title="bagasse ash">bagasse ash</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=self-compacting%20concrete" title=" self-compacting concrete"> self-compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=splitting%20tensile%20strength" title=" splitting tensile strength"> splitting tensile strength</a> </p> <a href="https://publications.waset.org/abstracts/80357/evaluation-of-fresh-strength-and-durability-properties-of-self-compacting-concrete-incorporating-bagasse-ash" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80357.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">352</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">2199</span> Structural Behavior of Lightweight Concrete Made With Scoria Aggregates and Mineral Admixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Shannag">M.

Properties considered included: workability, unit weight, compressive strength, and splitting tensile strength. Test results indicated that developing structural lightweight concretes (SLWC) using locally available Scoria lightweight aggregates and specific blends of silica fume and fly ash seems to be feasible. The stress-strain diagrams plotted for the structural LWC mixes developed in this investigation were comparable to a typical stress-strain diagram for normal weight concrete with relatively larger strain capacity at failure in case of LWC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lightweight%20concrete" title="lightweight concrete">lightweight concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=scoria" title=" scoria"> scoria</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=strain" title=" strain"> strain</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20fume" title=" silica fume"> silica fume</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title=" fly ash"> fly ash</a> </p> <a href="https://publications.waset.org/abstracts/1351/structural-behavior-of-lightweight-concrete-made-with-scoria-aggregates-and-mineral-admixtures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1351.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">511</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">2198</span> Design of Roller Compacting Concrete Pavement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Zarrin">O.

Therefore, the aggregates which are selected for the pavements are affected by higher flexural strength. Roller Compacting Concrete Pavement (RCCP) is not a new construction method. The other characteristic of this method is no bleeding and less shrinkage due to the lower amount of water. For this purpose, a roller is needed for placing and compacting. The surface of RCCP is not smooth; therefore, the most common use of this pavement is in an industrial zone with slower traffic speed which requires durable and tough pavement. For preparing a smoother surface, it can be achieved by asphalt paver. RCCP decrease the finishing cost because there are no bars, formwork, and the lesser labor need for placing the concrete. In this paper, different aspect of RCCP such as mix design, flexural, compressive strength and focus on the different part of RCCP on detail have been investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title="flexural strength">flexural strength</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=pavement" title=" pavement"> pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=asphalt" title=" asphalt"> asphalt</a> </p> <a href="https://publications.waset.org/abstracts/23282/design-of-roller-compacting-concrete-pavement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23282.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">625</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">2197</span> Utilization of Waste Marble Dust as a Viscosity Modifying Agent in Self Compacting Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shams%20Ul%20Khaliq">Shams Ul Khaliq</a>, <a href="https://publications.waset.org/abstracts/search?q=Mushtaq%20Zeb"> Mushtaq Zeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Fawad%20Bilal"> Fawad Bilal</a>, <a href="https://publications.waset.org/abstracts/search?q=Faizan%20Akbar"> Faizan Akbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Aamir%20Abbas"> Syed Aamir Abbas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self Compacting Concrete as the name implies--is the concrete requiring a very little or no vibration to fill the form homogeneously. Self Compacting Concrete (SCC) is defined by two primary properties: Ability to flow or deform under its own weight (with or without obstructions) and the ability to remain homogeneous while doing so. Flow ability is achieved by utilizing high range water reducing admixtures and segregation resistance is ensured by introducing a chemical viscosity modifying admixture (VMA) or increasing the amount of fines in the concrete. The study explores the use waste marble dust (WMD) to increase the amount of fines and hence achieve self-compatibility in an economical way, suitable for Pakistani construction industry. The study focuses on comparison of fresh properties of SCC containing varying amounts of waste marble dust (WMD) with that containing commercially available viscosity modifying admixture. The comparison is done at different dosages of super plasticizer keeping cement, water, coarse aggregate, and fine aggregate contents constant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self%20compacting%20concrete" title="self compacting concrete">self compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20marble%20dust%20%28WMD%29" title=" waste marble dust (WMD)"> waste marble dust (WMD)</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20ability" title=" flow ability"> flow ability</a>, <a href="https://publications.waset.org/abstracts/search?q=segregation%20resistance" title=" segregation resistance"> segregation resistance</a> </p> <a href="https://publications.waset.org/abstracts/49785/utilization-of-waste-marble-dust-as-a-viscosity-modifying-agent-in-self-compacting-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49785.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">327</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">2196</span> The Behavior of Self-Compacting Light Weight Concrete Produced by Magnetic Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moosa%20Mazloom">Moosa Mazloom</a>, <a href="https://publications.waset.org/abstracts/search?q=Hojjat%20Hatami"> Hojjat Hatami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this article is to access the optimal mix design of self-compacting light weight concrete. The effects of magnetic water, superplasticizer based on polycarboxylic-ether, and silica fume on characteristics of this type of concrete are studied. The workability of fresh concrete and the compressive strength of hardened concrete are considered here. For this purpose, nine mix designs were studied. The percentages of superplasticizer were 0.5, 1, and 2% of the weight of cement, and the percentages of silica fume were 0, 6, and 10% of the weight of cement. The water to cementitious ratios were 0.28, 0.32, and 0.36. The workability of concrete samples was analyzed by the devices such as slump flow, V-funnel, L box, U box, and Urimet with J ring. Then, the compressive strengths of the mixes at the ages of 3, 7, 28, and 90 days were obtained. The results show that by using magnetic water, the compressive strengths are improved at all the ages. In the concrete samples with ordinary water, more superplasticizer dosages were needed. Moreover, the combination of superplasticizer and magnetic water had positive effects on the mixes containing silica fume and they could flow easily. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20water" title="magnetic water">magnetic water</a>, <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20light%20weight%20concrete" title=" self-compacting light weight concrete"> self-compacting light weight concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20fume" title=" silica fume"> silica fume</a>, <a href="https://publications.waset.org/abstracts/search?q=superplasticizer" title=" superplasticizer"> superplasticizer</a> </p> <a href="https://publications.waset.org/abstracts/44599/the-behavior-of-self-compacting-light-weight-concrete-produced-by-magnetic-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44599.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">368</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">2195</span> Feasibility of a Biopolymer as Lightweight Aggregate in Perlite Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20A.%20Sayadi">Ali A.

Ultra-lightweight concrete can be applied as a filler and support material for the manufacturing of composite building materials. This paper is about the development of a stable and reproducible ultra-lightweight concrete with the inclusion of poly-lactic acid (PLA) beads and assessing the feasibility of PLA as a lightweight aggregate that will deliver advantages such as a more eco-friendly concrete and a non-petroleum polymer aggregate. In total, sixty-three samples were prepared and the effectiveness of mineral admixture, curing conditions, water-cement ratio, PLA ratio, EPS ratio and perlite ratio on compressive strength of perlite concrete are studied. The results show that PLA particles are sensitive to alkali environment of cement paste and considerably shrank and lost their strength. A higher compressive strength and a lower density was observed when expanded polystyrene (EPS) particles replaced PLA beads. In addition, a set of equations is proposed to estimate the water-cement ratio, cement content and compressive strength of perlite concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perlite%20concrete" title="perlite concrete">perlite concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=poly-lactic%20acid%20%28pla%29" title=" poly-lactic acid (pla)"> poly-lactic acid (pla)</a>, <a href="https://publications.waset.org/abstracts/search?q=expanded%20polystyrene%20%28eps%29" title=" expanded polystyrene (eps)"> expanded polystyrene (eps)</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a> </p> <a href="https://publications.waset.org/abstracts/50271/feasibility-of-a-biopolymer-as-lightweight-aggregate-in-perlite-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50271.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">314</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">2194</span> Polyolefin Fiber Reinforced Self-Compacting Concrete Replacing 20% Cement by Fly Ash</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suman%20Kumar%20Adhikary">Suman Kumar Adhikary</a>, <a href="https://publications.waset.org/abstracts/search?q=Zymantus%20Rudzionis"> Zymantus Rudzionis</a>, <a href="https://publications.waset.org/abstracts/search?q=Arvind%20Balakrishnan"> Arvind Balakrishnan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the behavior of concrete’s workability in a fresh state and compressive and flexural strength in a hardened state with the addition of polyolefin macro fibers.

Fresh concretes with low viscosity have a good flowability, whereas high viscosity has a lower flowability. Clearly, viscosity is directly linked to other parameters such as consistency, compaction, and workability of the concrete. The above parameters also depend very much on the energy induced during the mixing process and, of course, on the installation of the mixer itself. The University of Stuttgart has decided to investigate the influence of different mixing systems on the viscosity of various types of concrete, such as road concrete, self-compacting concrete, and lightweight concrete, using a rheometer and other testing methods. Each type is tested with three different mixers, and the rheological properties, namely consistency, and viscosity are determined. The aim of the study is to show that different types of concrete mixed with different types of mixers reach completely different yield points. Therefore, a 3 step procedure will be introduced. At first, various types of concrete mixtures and their differences are introduced. Then, the chosen suspension mixer and conventional mixers, which are going to be used in this paper, will be discussed. Lastly, the influence of the mixing system on the rheological properties of each of the select mix designs, as well as on fresh concrete, in general, will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rheological%20properties" title="rheological properties">rheological properties</a>, <a href="https://publications.waset.org/abstracts/search?q=flowability" title=" flowability"> flowability</a>, <a href="https://publications.waset.org/abstracts/search?q=suspension%20mixer" title=" suspension mixer"> suspension mixer</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a> </p> <a href="https://publications.waset.org/abstracts/118870/influence-of-the-mixer-on-the-rheological-properties-of-the-fresh-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118870.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">144</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">2188</span> Design Approach to Incorporate Unique Performance Characteristics of Special Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Devendra%20Kumar%20Pandey">Devendra Kumar Pandey</a>, <a href="https://publications.waset.org/abstracts/search?q=Debabrata%20Chakraborty"> Debabrata Chakraborty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The advancement in various concrete ingredients like plasticizers, additives and fibers, etc. has enabled concrete technologists to develop many viable varieties of special concretes in recent decades.

This paper focuses on usage of self-compacting concrete, high early strength concrete, structural lightweight concrete, fiber reinforced concrete, high performance concrete and ultra-high strength concrete in the structures. The modified properties of strength at various ages, flowability, porosity, equilibrium density, flexural strength, elasticity, permeability etc. need to be carefully studied and incorporated into the design of the structures. The paper demonstrates various mixture combinations and the concrete properties that can be leveraged. The selection of such products based on the end use of structures has been proposed in order to efficiently utilize the modified characteristics of these concrete varieties. The study involves mapping the characteristics with benefits and savings for the structure from design perspective. Self-compacting concrete in the structure is characterized by high shuttering loads, better finish, and feasibility of closer reinforcement spacing. The structural design procedures can be modified to specify higher formwork strength, height of vertical members, cover reduction and increased ductility. The transverse reinforcement can be spaced at closer intervals compared to regular structural concrete. It allows structural lightweight concrete structures to be designed for reduced dead load, increased insulation properties. Member dimensions and steel requirement can be reduced proportionate to about 25 to 35 percent reduction in the dead load due to self-weight of concrete. Steel fiber reinforced concrete can be used to design grade slabs without primary reinforcement because of 70 to 100 percent higher tensile strength. The design procedures incorporate reduction in thickness and joint spacing. High performance concrete employs increase in the life of the structures by improvement in paste characteristics and durability by incorporating supplementary cementitious materials. Often, these are also designed for slower heat generation in the initial phase of hydration. The structural designer can incorporate the slow development of strength in the design and specify 56 or 90 days strength requirement. For designing high rise building structures, creep and elasticity properties of such concrete also need to be considered. Lastly, certain structures require a performance under loading conditions much earlier than final maturity of concrete. High early strength concrete has been designed to cater to a variety of usages at various ages as early as 8 to 12 hours. Therefore, an understanding of concrete performance specifications for special concrete is a definite door towards a superior structural design approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20performance%20concrete" title="high performance concrete">high performance concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20concrete" title=" special concrete"> special concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20design" title=" structural design"> structural design</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20lightweight%20concrete" title=" structural lightweight concrete"> structural lightweight concrete</a> </p> <a href="https://publications.waset.org/abstracts/81287/design-approach-to-incorporate-unique-performance-characteristics-of-special-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81287.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">2187</span> Mechanical Properties of Self-Compacting Concrete with Three-Dimensional Steel Fibres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeffri%20Ramli">Jeffri Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Brabha%20Nagaratnam"> Brabha Nagaratnam</a>, <a href="https://publications.waset.org/abstracts/search?q=Keerthan%20Poologanathan"> Keerthan Poologanathan</a>, <a href="https://publications.waset.org/abstracts/search?q=Wai%20Ming%20Cheung"> Wai Ming Cheung</a>, <a href="https://publications.waset.org/abstracts/search?q=Thadshajini%20Suntharalingham"> Thadshajini Suntharalingham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fiber-reinforced self-compacting concrete (FRSCC) combines the benefits of SCC of high flowability and randomly dispersed short fibres together in one single concrete. Fibres prevent brittle behaviour and improve several mechanical properties of SCC. In this paper, an experimental investigation of the effect of three-dimensional (3D) fibres on the mechanical properties of SCC has been conducted. Seven SCC mixtures, namely SCC with no fibres as a reference mix, and six 3D steel fibre reinforced SCC mixes were prepared. Two different sizes of 3D steel fibres with perimeters of 115 mm and 220 mm at different fibre contents of 1%, 2%, and 3% (by cement weight) were considered. The mechanical characteristics were obtained through compressive, splitting tensile, and flexural strength tests. The test results revealed that the addition of 3D fibres improves the mechanical properties of SCC. <p class="card-text"><strong>Keywords:</strong> <a
