In this study concrete containing 10%, 15% and 20% RHA as cement replacement and water to binder ratio of 0.25 were investigated. The results show that increasing amount of RHA increases the dosage of superplasticizer to maintain similar workability. Partial replacement of cement with RHA did not increase the early age compressive strength of concrete. However, concrete containing RHA showed higher compressive strength at later ages. The results showed that compressive strength of concrete in the 90-115 MPa range can be obtained at 28 curing days and the durability properties of RHA concrete performed better than that of control concrete. The water absorption of concrete incorporating 15% RHA exhibited the lowest value. The porosity of concrete is consistent with water absorption whereby higher replacement of RHA decreased the porosity of concrete. There is a positive correlation between reducing porosity and increasing compressive strength of high strength high performance concrete. The results also indicate that up to 20% of RHA incorporation could be advantageously blended with cement without adversely affecting the strength and durability properties of concrete. <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=durability" title=" durability"> durability</a>, <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=rice%20husk%20ash" title=" rice husk ash"> rice husk ash</a> </p> <a href="https://publications.waset.org/abstracts/47128/effect-of-rice-husk-ash-on-strength-and-durability-of-high-strength-high-performance-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47128.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">345</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">9291</span> The Effects of Various Curing Compounds on the Mechanical Characteristics of Roller Compacted Concrete Pavements (RCCP)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azadeh%20Askarinejad">Azadeh Askarinejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Parmida%20Hayati"> Parmida Hayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Parham%20Hayati"> Parham Hayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Parchami"> Reza Parchami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Curing is a very important factor in the ultimate strength and durability of roller compacted concrete pavements (RCCP). Curing involves keeping the concrete is saturated or close to saturation point. Since maintaining concrete moisture has a significant impact on its mechanical properties, permeability and durability, curing is important. The most common procedure for curing of roller compacted concrete is using a white pigmented curing compound. This method is effective, economical and fast. In the present study, different curing compounds were applied on concrete specimens and the results of their effects on the mechanical properties were compared with each other and usual methods of curing in order to select appropriate materials and methods of curing for RCCP construction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curing%20compounds" title="curing compounds">curing compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=roller%20compacted%20concrete%20pavements" title=" roller compacted concrete pavements"> roller compacted concrete pavements</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability "> durability </a> </p> <a href="https://publications.waset.org/abstracts/19721/the-effects-of-various-curing-compounds-on-the-mechanical-characteristics-of-roller-compacted-concrete-pavements-rccp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19721.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">622</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">9290</span> Experimental Study of Mechanical and Durability Properties of HPC Made with Binary Blends of Cement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vatsal%20Patel">Vatsal Patel</a>, <a href="https://publications.waset.org/abstracts/search?q=Niraj%20Shah"> Niraj Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the research reported in this paper is to assess the Strength and durability performance of High Performance Concrete containing different percentages of waste marble powder produced from marble industry.

Specimens of Concrete M100 grade with water/binder ratio 0.239, with Foundry Slag (FD) varying from 0 to 50% and with optimum quantity of AF(15%) were casted and tested for durability properties such as Water absorption, water permeability, resistance to sulphate attack, alkali attack and nitrate attack of HSC at the age of 7, 14, 28, 56 and 90 days. Substitution of fine aggregates (FA) with up to 45% of foundry slag(FD) content and cement with 15% substitution and addition of alccofine showed an excellent resistance against durability properties at all ages but showed a decrease in these properties with 50% of FD contents. Loss of weight in concrete samples due to sulphate attack, alkali attack and nitrate attack of HSC at the age of 365 days was compared with loss in compressive strength. Correlation between loss in weight and loss in compressive strength in all the tests was found to be excellent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alccofine" title="alccofine">alccofine</a>, <a href="https://publications.waset.org/abstracts/search?q=alkali%20attack" title=" alkali attack"> alkali attack</a>, <a href="https://publications.waset.org/abstracts/search?q=foundry%20slag" title=" foundry slag"> foundry slag</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20strength%20concrete" title=" high strength concrete"> high strength concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrate%20attack" title=" nitrate attack"> nitrate attack</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20absorption" title=" water absorption"> water absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20permeability" title=" water permeability"> water permeability</a> </p> <a href="https://publications.waset.org/abstracts/61016/effect-of-waste-foundry-slag-and-alccofine-on-durability-properties-of-high-strength-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61016.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">331</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">9286</span> Impact of Locally Available Recycled Concrete Aggregate on Concrete’s Mechanical and Durability Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Robert%20Bu%C5%A1i%C4%87">Robert Bušić</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Mili%C4%8Devi%C4%87"> Ivana Miličević</a>, <a href="https://publications.waset.org/abstracts/search?q=Larisa%20%C5%A0arga%C4%8D"> Larisa Šargač</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The construction industry generates a large amount of waste, which poses a challenge for disposal and often requires significant areas for landfill. Therefore, recycling construction waste has become imperative. This study focuses on investigating the use of locally available recycled concrete as a substitute for traditional aggregates and analyzing the impact of this change on the mechanical and durability properties of concrete. The research begins with the crushing of locally available waste concrete, followed by sieving and sorting the aggregate into different fractions. Four concrete mix designs were created, with one serving as a reference mixture without recycled aggregate, while the remaining three mixes included recycled aggregate in varying proportions. The experimental part includes testing the key properties of concrete in both fresh and hardened states, including slump and flow tests, compressive strength, static modulus of elasticity, and shrinkage of the concrete, with the aim of assessing the impact of locally available recycled aggregate on concrete properties. By using experimental testing methods, the results were compared with conventional concrete, providing deeper insights into the potential advantages and disadvantages of using locally available recycled concrete in various construction projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20aggregate" title=" recycled aggregate"> recycled aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/194656/impact-of-locally-available-recycled-concrete-aggregate-on-concretes-mechanical-and-durability-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194656.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">7</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">9285</span> An Experimental Study on Service Life Prediction of Self: Compacting Concrete Using Sorptivity as a Durability Index</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Girish">S.

The processes of deterioration in concrete are mediated largely by water. There is a strong interest in finding a better way of assessing the material properties of concrete in terms of durability. Water sorptivity is a useful single material property which can be one of the measures of durability useful in service life planning and prediction, especially in severe environmental conditions. This paper presents the results of the comparative study of sorptivity of Self-Compacting Concrete (SCC) with conventionally vibrated concrete. SCC is a new, special type of concrete mixture, characterized by high resistance to segregation that can flow through intricate geometrical configuration in the presence of reinforcement, under its own mass, without vibration and compaction. SCC mixes were developed for the paste contents of 0.38, 0.41 and 0.43 with fly ash as the filler for different cement contents ranging from 300 to 450 kg/m3. The study shows better performance by SCC in terms of capillary absorption. The sorptivity value decreased as the volume of paste increased. The use of higher paste content in SCC can make the concrete robust with better densification of the micro-structure, improving the durability and making the concrete more sustainable with improved long term performance. The sorptivity based on secondary absorption can be effectively used as a durability index to predict the time duration required for the ingress of water to penetrate the concrete, which has practical significance. <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=service%20life%20prediction" title=" service life prediction"> service life prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=sorptivity" title=" sorptivity"> sorptivity</a>, <a href="https://publications.waset.org/abstracts/search?q=volume%20of%20paste" title=" volume of paste"> volume of paste</a> </p> <a href="https://publications.waset.org/abstracts/79405/an-experimental-study-on-service-life-prediction-of-self-compacting-concrete-using-sorptivity-as-a-durability-index" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79405.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">321</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">9284</span> Durability of Lightweight Concrete Material Made from Date Palma Seeds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Almograbi">Mohammed Almograbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Libya is one of the largest producers of dates from date palm, generating about 60000 tonnes of date palm seeds (DPS) annually. 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.

It is now common knowledge that the transport properties of a concrete, i.e; permeability and chloride diffusion coefficient are important indicators of its durability. The development of microcracking in concrete structures leads to significant permeability and to durability problems as a result. The main objective of the study presented in this paper is to investigate the influence of mineral admixtures and impact of compressive cracks by mechanical uniaxial compression up to 80% of the ultimate strength on transport properties of self-compacting concrete (SCC) manufactured with the eco-materials (metakaolin, fly ash, slag HF). The chloride resistance and binding capacity of the different SCCs produced with the different admixtures in damaged and undamaged state are measured using a chloride migration test accelerated by an external applied electrical field. Intrinsic permeability is measured using the helium gas and one permeameter at constant load. Klinkenberg approach is used for the determination of the intrinsic permeability. Based on the findings of this study, the use of mineral admixtures increases the resistance of SCC to chloride ingress and reduces their permeability. From the impact of mechanical damage, we show that the Gas permeability is more sensitive of concrete damaged than chloride diffusion. A correlation is obtained between the intrinsic permeability and chloride migration coefficient according to the damage variable for the four studied mixtures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SCC" title="SCC">SCC</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20durability" title=" concrete durability"> concrete durability</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20properties" title=" transport properties"> transport properties</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20permeability" title=" gas permeability"> gas permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=chloride%20diffusion" title=" chloride diffusion"> chloride diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20damage" title=" mechanical damage"> mechanical damage</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20admixtures" title=" mineral admixtures"> mineral admixtures</a> </p> <a href="https://publications.waset.org/abstracts/48587/effect-of-mineral-admixtures-on-transport-properties-of-sccs-composites-influence-of-mechanical-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48587.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">9282</span> Mechanical, Physical and Durability Properties of Cement Mortars Added with Recycled PP/PE-Based Food Packaging Waste Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Livia%20Guerini">Livia Guerini</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Paglia"> Christian Paglia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Switzerland, only a fraction of plastic waste from food packaging is collected and recycled for further use in the food industry. Therefore, reusing these waste plastics for building applications can be an attractive alternative to disposal in order to reduce the problem of waste management and to make up for the depletion of raw materials needed for construction. In this study, experiments were conducted on the mechanical properties (compressive and flexural strength, elastic modulus), physical properties (density, workability, porosity, and water permeability) and durability (freeze/thaw resistance) of cementitious mortars with additions of recycled low-/high-density polyethylene (LDPE/HDPE)/ polypropylene (PP) regrind (addition of 5% and 10% by weight) and LDPE sheets (addition of 0.5% and 1.5% by weight) coming from food packaging. The results show that as the addition of plastic material increases, the density and mechanical properties of the mortars decrease compared to conventional ones. Porosity is similar in all the mixtures made, while the workability and the permeability are affected not only by the amount added but also by the shape of the plastic aggregate. Freeze/thaw resistance, on the other hand, is significantly higher in mortars with plastic aggregates than in traditional mortar. This feature may be interesting for the realization of outdoor mortars in cold environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20packaging%20waste" title="food packaging waste">food packaging waste</a>, <a href="https://publications.waset.org/abstracts/search?q=durability%20properties" title=" durability properties"> durability properties</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=mortar" title=" mortar"> mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20PE" title=" recycled PE"> recycled PE</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20PP" title=" recycled PP"> recycled PP</a> </p> <a href="https://publications.waset.org/abstracts/144698/mechanical-physical-and-durability-properties-of-cement-mortars-added-with-recycled-pppe-based-food-packaging-waste-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144698.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">145</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">9281</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.

To achieve this, an ANNs model is developed to predict the durability of self compacting concrete which is expressed in terms of chloride ions permeability in accordance with ASTM C1202-97 or AASHTO T277. Database gathered from the literature for the training and testing the model. A sensitivity analysis was also conducted using the trained and tested ANN model to investigate the effect of fly ash on the durability of SCC. The results indicate that the developed model is reliable and accurate. the durability of SCC expressed in terms of total charge passed over a 6-h period can be significantly improved by using at least 25% fly ash as replacement of cement.

We investigated the physical and microscopic properties of fresh concrete while adjusting several of the fabrication parameters, such as the constituent makeup and thickness of RFA pre-coatings. The study is divided into two parts. The first part involves mortar testing in which the RFA used for coating had a water/cement ratio of 0.5 and fly ash, slag, and PVA viscosity of 5~6cps, 21~26cps, 25~30cps, or 44~50cps. In these tests, 100% of the natural fine aggregate was replaced by RCA. The second part of the study involved the mixing of concrete with 25% FRA, which was respectively coated with fly ash, slag, or PVA at a viscosity of 44~50cps. In these tests, the water/cement ratio was either .4 or 0.6. The major findings in this study are summarized as follows: Coating RFA coated with fly ash and PVA was shown to increase flow in the fresh concrete; however, the coating of FRA with slag resulted in a slight decrease in flow. Coating FRA with slag was shown to improve the compressive and splitting strength to a greater degree than that achieved by coating FRA with fly ash and PVA. The mechanical properties of concrete mixed with slag were shown to increase with the thickness of the coating. Coating FRA with slag was also shown to enhance the durability of the concrete, regardless of the water/cement ratio. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recycled%20fine%20aggregates" title="recycled fine aggregates">recycled fine aggregates</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-coated" title=" pre-coated"> pre-coated</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=slag" title=" slag"> slag</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-coated%20thickness" title=" pre-coated thickness"> pre-coated thickness</a> </p> <a href="https://publications.waset.org/abstracts/38085/mechanical-properties-and-durability-of-concretes-manufactured-using-pre-coated-recycled-fine-aggregate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38085.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">324</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">9279</span> Evaluation of Durability Performance for Bio-Energy Co-Product</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bo%20Yang">Bo Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hali%CC%87l%20Ceylan"> Hali̇l Ceylan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ulvi%CC%87%20Uzer"> Ali Ulvi̇ Uzer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This experimental study was performed to investigate the effect of biofuel co-products (BCPs) with sulfur-free lignin addition on the unconsolidated on strength and durability behavior in pavement soil stabilization subjected to freezing–thawing cycles.

Over the last twenty years, phenomenal advances have taken place in the research and application of UHPC. Recently, the approach is to improve UHPC sustainability by reducing its embodied energy. First of all, this goal can be achieved by reducing Portland cement dosage. In this work, an experimental investigation was carried out to characterize the mechanical behavior and durability of UHPCs prepared by reducing the cement amount by 30% in order to verify the impact of lower cement content and higher water-to-cement ratio on both mechanical performance and durability, if any. Eight different UHPC mixtures were compared, with two different cement dosages (either 1000 or 700 kg) and four different brass-coated steel fibres dosages (0 - 50 - 100 - 150 kg), in terms of 28-day compressive and flexural strengths. Then, the mixtures prepared with the lower cement content were further investigated in terms of abrasion resistance, water absorption, freezing and thawing cycles, and resistance to sulphate attack. Results obtained showed the feasibility of reducing cement dosage without compromising mechanical performance and UHPC's extraordinary durability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abrasion%20resistance" title="abrasion resistance">abrasion resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=eco-efficiency" title=" eco-efficiency"> eco-efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze-thawing%20cycles" title=" freeze-thawing cycles"> freeze-thawing cycles</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20fibres" title=" steel fibres"> steel fibres</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphate%20exposure" title=" sulphate exposure"> sulphate exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=UHPC" title=" UHPC"> UHPC</a> </p> <a href="https://publications.waset.org/abstracts/163828/mechanical-characterization-and-durability-of-eco-efficient-ultra-high-performance-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163828.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">76</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">9277</span> Durability Assessment of Nanocomposite-Based Bone Fixation Device Consisting of Bioabsorbable Polymer and Ceramic Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jisoo%20Kim">Jisoo Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin-Young%20Choi"> Jin-Young Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=MinSu%20Lee"> MinSu Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunmook%20Lee"> Sunmook Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effects of ceramic nanoparticles on the improvement of durability of bone fixation devices have been investigated by assessing the durability of nanocomposite materials consisting of bioabsorbable polymer and ceramic nanoparticles, which could be applied for bone fixation devices such as plates and screws. Various composite ratios were used for the synthesis of nanocomposite materials by blending polylactic acid (PLA) and polyglycolic acid (PGA) as bioabsorbable polymer, and hydroxyapatite (HA) and tri-calcium phosphate (TCP) as ceramic nanoparticles. It was found that the addition of ceramic nanoparticles significantly enhanced the mechanical properties of the bone fixation devices compared to those fabricated with pure biopolymers. Particularly, the layer-by-layer approach for the fabrication of nanocomposites also had an effect on the improvement of bending strength. Durability tests were performed by measuring the changes in the bending strength of nanocomposite samples under varied temperature conditions for the accelerated degradation tests. It was found that Weibull distribution was the most proper one for describing the life distribution of devices in the present study. The mean lifetime was predicted by adopting Arrhenius Eq.

The use of this by-product called pomace has potentials to reduce cost of aquafeed. Pineapple pomace collected after juice extraction was dried and milled. The interactive effects of feeding rate (1.28, 1.44 and 1.60kg/min), screw speed (305, 355 and 405rpm), moisture content (16, 19 and 22%), temperatures (60, 80, 100 and 120°C), cutting speed (1300, 1400 and 1500rpm), pomace inclusion ratio (5, 10, 15, 20%) and open surface die (50, 75 and 100%) on the extrudate physical properties (bulk density, unit density, expansion ratio, durability and floatability) were investigated using optimal custom design (OCD) matrix and response surface methodology. The predicted values were found to be in good agreement with the experimental values for, expansion ratio, durability and floatability (R2 = 0.7970; 0.9264; 0.9098 respectively) with the exceptions of unit density and bulk density (R2 = 0.1639; 0.2768 respectively). All the extrudates showed relatively high floatability, durability. The inclusion of pineapple pomace produced less expanded and more compact textured extrudates. Results indicated that increased in the value of pineapple pomace, screw speed, feeding rate decreased unit density, bulk density, expansion ratio, durability and floatability of the extrudate. However, increasing moisture content of feed mash resulted in increase unit density and bulk density. Addition of extrusion temperature and cutting speed increased the floatability and durability of extrudate. The proportion of pineapple pomace in aquafeed extruded product was observed to have significantly lower effect on the selected responses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquafeed" title="aquafeed">aquafeed</a>, <a href="https://publications.waset.org/abstracts/search?q=extrusion" title=" extrusion"> extrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20properties" title=" physical properties"> physical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=pineapple%20pomace" title=" pineapple pomace"> pineapple pomace</a>, <a href="https://publications.waset.org/abstracts/search?q=waste" title=" waste"> waste</a> </p> <a href="https://publications.waset.org/abstracts/68817/effect-of-processing-parameters-on-the-physical-properties-of-pineapple-pomace-based-aquafeed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68817.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">271</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">9275</span> Improved Clothing Durability as a Lifespan Extension Strategy: A Framework for Measuring Clothing Durability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kate%20E%20Morris">Kate E Morris</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Sumner"> Mark Sumner</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Taylor"> Mark Taylor</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Joynes"> Amanda Joynes</a>, <a href="https://publications.waset.org/abstracts/search?q=Yue%20Guo"> Yue Guo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Garment durability, which encompasses physical and emotional factors, has been identified as a critical ingredient in producing clothing with increased lifespans, battling overconsumption, and subsequently tackling the catastrophic effects of climate change. Eco-design for Sustainable Products Regulation (ESPR) and Extended Producer Responsibility (EPR) schemes have been suggested and will be implemented across Europe and the UK which might require brands to declare a garment’s durability credentials to be able to sell in that market. There is currently no consistent method of measuring the overall durability of a garment. Measuring the physical durability of garments is difficult and current assessment methods lack objectivity and reliability or don’t reflect the complex nature of durability for different garment categories. This study presents a novel and reproducible methodology for testing and ranking the absolute durability of 5 commercially available garment types, Formal Trousers, Casual Trousers, Denim Jeans, Casual Leggings and Underwear. A total of 112 garments from 21 UK brands were assessed. Due to variations in end use, different factors were considered across the different garment categories when evaluating durability. A physical testing protocol was created, tailored to each category, to dictate the necessary test results needed to measure the absolute durability of the garments. Multiple durability factors were used to modulate the ranking as opposed to previous studies which only reported on single factors to evaluate durability. The garments in this study were donated by the signatories of the Waste Resource Action Programme’s (WRAP) Textile 2030 initiative as part of their strategy to reduce the environmental impact of UK fashion. This methodology presents a consistent system for brands and policymakers to follow to measure and rank various garment type’s physical durability. Furthermore, with such a methodology, the durability of garments can be measured and new standards for improving durability can be created to enhance utilisation and improve the sustainability of the clothing on the market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circularity" title="circularity">circularity</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=garment%20testing" title=" garment testing"> garment testing</a>, <a href="https://publications.waset.org/abstracts/search?q=ranking" title=" ranking"> ranking</a> </p> <a href="https://publications.waset.org/abstracts/187429/improved-clothing-durability-as-a-lifespan-extension-strategy-a-framework-for-measuring-clothing-durability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187429.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">35</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">9274</span> Experimental Investigation of the Effect of Glass Granulated Blast Furnace Slag on Pavement Quality Concrete Pavement Made of Recycled Asphalt Pavement Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imran%20Altaf%20Wasil">Imran Altaf Wasil</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinesh%20Ganvir"> Dinesh Ganvir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to a scarcity of virgin aggregates, the use of reclaimed asphalt pavement (RAP) as a substitute for natural aggregates has gained popularity. Despite the fact that RAP is recycled in asphalt pavement, there is still excess RAP, and its use in concrete pavements has expanded in recent years. According to a survey, 98 percent of India's pavements are flexible. As a result, the maintenance and reconstruction of such pavements generate RAP, which can be reused in concrete pavements as well as surface course, base course, and sub-base of flexible pavements. Various studies on the properties of reclaimed asphalt pavement and its optimal requirements for usage in concrete has been conducted throughout the years. In this study a total of four different mixes were prepared by partially replacing natural aggregates by RAP in different proportions. It was found that with the increase in the replacement level of Natural aggregates by RAP the mechanical and durability properties got reduced. In order to increase the mechanical strength of mixes 40% Glass Granulated Blast Furnace Slag (GGBS) was used and it was found that with replacement of cement by 40% of GGBS, there was an enhancement in the mechanical and durability properties of RAP inclusive PQC mixes. The reason behind the improvement in the properties is due to the processing technique used in order to remove the contaminant layers present in the coarse RAP aggregates. The replacement level of Natural aggregate with RAP was done in proportions of 20%, 40% and 60% along with the partial replacement of cement by 40% GGBS. It was found that all the mixes surpassed the design target value of 40 MPa in compression and 4.5 MPa in flexure making it much more economical and feasible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reclaimed%20asphalt%20pavement" title="reclaimed asphalt pavement">reclaimed asphalt pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement%20quality%20concrete" title=" pavement quality concrete"> pavement quality concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=glass%20granulated%20blast%20furnace%20slag" title=" glass granulated blast furnace slag"> glass granulated blast furnace slag</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20and%20durability%20properties" title=" mechanical and durability properties"> mechanical and durability properties</a> </p> <a href="https://publications.waset.org/abstracts/150742/experimental-investigation-of-the-effect-of-glass-granulated-blast-furnace-slag-on-pavement-quality-concrete-pavement-made-of-recycled-asphalt-pavement-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150742.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">116</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">9273</span> A Review on Geomembrane Characteristics and Application in Geotechnical Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Ghavam%20Shirazi">Sandra Ghavam Shirazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Komeil%20Valipourian"> Komeil Valipourian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Golhashem"> Mohammad Reza Golhashem </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper represents the basic idea and mechanisms associated with the durability of geomembranes and discusses the factors influencing the service life and temperature of geomembrane liners.

Non-styolitic marbleized limestone which not contains styolitic surfaces. The current study aims to study different factors controlling durability of non-styolitic marbleized limestone against salt crystallization weathering. The achievement aim of the research was required nine representative samples were collected from the studied areas. Three samples from each of the studied areas. The studied samples was characterized by various instrumental methods before salt weathering, to determine its mineralogical composition, chemical composition and pore physical properties respectively. The obtained results revealed that both of Duwi and Delga studied samples nearly have the same average ∆M% 1.63 and 1.51 respectively and consequently A.I. stage of deformation. On the other hand, average ∆M% of Wata studied samples is 0.29 i.e. lower than two other studied areas. Wata studied samples are more durable against salt crystallization test than Duwi and Delga. The difference in salt crystallization durability may be resulted from one of the following factors: Microscopic textural effect as both of micrite and skeletal percent are in directly proportional to durability of stones to salt weathering. Dolomite mineral present as a secondary are in indirectly proportional to durability of stones to salt weathering. Increase in MgO% also associated with decrease the durability of studied samples against salt crystallization test. Finally, all factors affecting positively against salt crystallization test presents in Wadi Wata studied samples rather than others two areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marbleized%20limestone" title="marbleized limestone">marbleized limestone</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20weathering" title=" salt weathering"> salt weathering</a>, <a href="https://publications.waset.org/abstracts/search?q=Wata" title=" Wata"> Wata</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20weathering" title=" salt weathering"> salt weathering</a> </p> <a href="https://publications.waset.org/abstracts/11044/factors-controlling-durability-of-some-egyptian-non-stylolitic-marbleized-limestone-to-salt-weathering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11044.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">9270</span> Manufacturing of Nano Zeolite by Planetary Ball Mill and Investigation of the Effects on Concrete </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Kosari">Kourosh Kosari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is engineering the properties of concrete containing natural nano zeolite as supplementary cementitious material in the blended Portland-cement based binder in amounts of 5,7 and 10% by mass.

SiO₂ particles in cement act as centers of nucleation, as a filler or as pozzolan material. In this regard, silica improves the microstructure of cementitious composites, increases the mechanical properties, and finally also results into improved durability of the final products. Improved properties of cementitious composites may lead to better structural efficiency, which, together with increased durability, results into increased sustainability signature of structures made with this kind of materials. The aim of the present work was to investigate the influence of silica on the properties of cement. Fly ash (as received and mechanically activated) and synthetized silica (sol-gel method using TEOS as precursor) was used in the investigation as source of silica. Four types of cement mixtures were investigated (reference cement paste, cement paste with addition of 15wt.% as-received fly ash, cement paste with 15 wt.% mechanically activated fly ash and cement paste with 14wt.% mechanically activated fly ash and 1 wt.% silica). The influence of silica on setting time and mechanical properties (2, 7 and 28 days) was followed. As a matter of fact it will be shown that cement paste with composition 85 wt. % cement, 14 wt.% mechanically activated fly ash and 1 wt. % SiO₂ obtained by the sol-gel method was the best performing one, with increased compressive and flexure strength by 9 and 10 % respectively, as compared to the reference mixture.

Among the different resins, a methacrylate-based type of acrylic resin significantly inhibited the rebar corrosion. This was mainly caused by the relatively high pH of the resin and the resin aqueous solution. This resin also exhibited a relatively high sealing performance, in particular after exposing the resin to durability tests. The corrosion inhibition behaviour and the sealing properties after the exposition to durability tests were maintained up to one year. The other resins either promoted the corrosion of the rebar and/or exhibited relatively low sealing properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acrylic%20resin" title="acrylic resin">acrylic resin</a>, <a href="https://publications.waset.org/abstracts/search?q=sealing%20performance" title=" sealing performance"> sealing performance</a>, <a href="https://publications.waset.org/abstracts/search?q=rebar%20corrosion" title=" rebar corrosion"> rebar corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=materials" title=" materials"> materials</a> </p> <a href="https://publications.waset.org/abstracts/113691/the-performance-and-the-induced-rebar-corrosion-of-acrylic-resins-for-injection-systems-in-concrete-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113691.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">131</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">9267</span> Mechanical Strengths of Self-Compacting Mortars Prepared with the Pozzolanic Cement in Aggressive Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Saidi">M.

Order to evaluate durability, mortars were subjected to chemical attacks in various aggressive environments, a solution of a mixture of nitric acid and ammonium nitrate (HNO<sub>3</sub> + NH<sub>4</sub>NO<sub>3</sub>) and a magnesium sulfate salt solution (MgSO<sub>4</sub>)) with a concentration of 10%, for a period of one month. This study is complemented by a comparative study of the durability of mortars elaborated with sulphate resistant cement (SRC). The results show that these mortars develop long-term, mechanical and chemical resistance better than mortars based Portland cement with 5% gypsum (CEM 1) and SRC. We found that the mass losses are lowest in mortars elaborated with pozzolanic cement (30% substitution with SSB<sub>2</sub>) in both of chemical attack solutions (3.28% in the solution acid and 1.16% in the salt solution) and the compressive strength gains of 14.68% and 8.5% respectively in the two media. This is due to the action of pozzolan which fixes portlandite to form hydrated calcium silicate (CSH) from the hydration of tricalcic silicate (C<sub>3</sub>S). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aggressive%20environments" title="aggressive environments">aggressive environments</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20strengths" title=" mechanical strengths"> mechanical strengths</a>, <a href="https://publications.waset.org/abstracts/search?q=pozzolanic%20cement" title=" pozzolanic cement"> pozzolanic cement</a>, <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20mortar" title=" self-compacting mortar"> self-compacting mortar</a> </p> <a href="https://publications.waset.org/abstracts/59732/mechanical-strengths-of-self-compacting-mortars-prepared-with-the-pozzolanic-cement-in-aggressive-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59732.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">235</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">9266</span> Study on the Strength and Durability Properties of Ternary Blended Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Athira%20Babu">Athira Babu</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Nazeer"> M.

The durability and strength characteristics of concrete make it more desirable among any other construction materials. The manufacture and use of concrete produces wide range of environmental and social consequences. The major component in concrete, cement accounts for roughly 5 % of global CO2 emissions. In order to improve the environmental friendliness of concrete, suitable substitutes are added to concrete. The present study deals with GGBS and silica fume as supplementary cementitious materials. The strength and durability studies were conducted in this ternary blended concrete. Several mixes were adopted with varying percentages of Silica Fume i.e., 5%, 10% and 15%. Binary mix with 50% GGBS was also prepared. GGBS content has been kept constant for the rest of mixes. There is an improvement in compressive strength with addition of Silica Fume.Maximum workability, split tensile strength, modulus of elasticity, flexural strength and impact resistance are obtained for GGBS binary blend. For durability studies, maximum sulphate resistance,carbonation resistance andresistance to chloride ion penetration are obtained for ternary blended concrete. Partial replacement of GGBS and Silica Fume reduces the environmental effects, produces economical and eco-friendly concrete. The study showed that for strength characteristics, binary blended concrete showed better performance while for durability study ternary blend performed better. <p
