composites prepared from waste silk fibers and recycled polycarbonate polymer (used compacted boards) at four levels of 0, 10, 20, and 30% (silk fibers) and using 2% N- 2-Aminoethyl-3-Aminopropyltrimethoxysilane was investigated as a coupling agent and melt process method. Silk fibers (carpet weaving waste) with dimensions of 8-18 mm were prepared, and recycled polymer with 9 mesh grading was ground. Production boards in 3 thicknesses, 3 mm (tensile test samples), 5 mm (bending test samples, water absorption, and thickness shrinkage), 7 mm (impact resistance test samples) ) with a specific weight of 1 gram per cubic centimeter, hot pressing time and temperature of 12 minutes and 190 degrees Celsius with a pressure of 130 bar, cold pressing time of 6 minutes with a pressure of 50 bar and using the coupling agent N- (2- Aminoethyl)-3-aminopropyltrimethoxysilane was prepared in a constant amount of 2% of the dry weight of the filler. The results showed that, in general, by adding silk fibers to the base polymer, compared to the control samples (pure recycled polycarbonate polymer) and also by increasing the amount of silk fibers, almost all the resistances increased. The amount of water absorption of the constructed composite increased with the increase in the amount of silk fibers, and the thickness absorption was equal to 0% even after 72 hours of immersion in water. The thermal resistance of the pure recycled polymer was higher than the prepared composites, and by adding silk fibers to the base polymer and also by increasing the amount of silk fibers from 10 to 30%, the thermal resistance of the composites decreased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20composite" title="wood composite">wood composite</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20polycarbonate" title=" recycled polycarbonate"> recycled polycarbonate</a>, <a href="https://publications.waset.org/abstracts/search?q=silk%20fibers" title=" silk fibers"> silk fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a> </p> <a href="https://publications.waset.org/abstracts/154382/investigating-the-characteristics-of-multi-plastic-composites-prepared-from-a-mixture-of-silk-fibers-and-recycled-polycarbonate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154382.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">92</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">416</span> Thermal Ageing Effect on Mechanical Behavior of Polycarbonate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Babou">H.

A simple compression tests, micro hardness and an IRTF analysis were completed in order to characterize the response of material on specimens after ageing at a temperature of order 100 C° and for serval maintain duration 72, 144 and 216 hours. These investigations showed a decrease of the intrinsic properties of polycarbonate (Young modulus, yield stress, etc.); the superposition of spectra IRTF shows that the intensity of chemical connections C=C, C-O, CH3 and C-H are influenced by the duration of thermal ageing; in addition, an increase of 30 % of micro hardness was detected after 216 hour of ageing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amorphous%20polymer" title="amorphous polymer">amorphous polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=polycarbonate" title=" polycarbonate"> polycarbonate</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20behavior" title=" mechanical behavior"> mechanical behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=compression%20test" title=" compression test"> compression test</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20ageing" title=" thermal ageing"> thermal ageing</a> </p> <a href="https://publications.waset.org/abstracts/25171/thermal-ageing-effect-on-mechanical-behavior-of-polycarbonate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25171.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">409</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">415</span> Masonry Blocks with Recycled Aggregates and Recycled Glass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Y.%20Matar">Pierre Y.

The recycled aggregates obtained by crushing the demolished concrete can be used as a substitute of natural aggregates. Another major C&D waste is the flat glass. This glass can be also recycled and used as an aggregate substitute. The objective of this study is to determine the influence of the use of recycled concrete aggregates and recycled glass on the compressive strength and fire resistance of precast concrete masonry blocks. Tests are carried out on four series of blocks whose compositions include different percentages of recycled aggregates and recycled glass and one series of reference blocks whose composition consists of exclusively natural aggregates. The recycled coarse aggregates and recycled glass have 6.3/12.5 mm fraction and the natural aggregates have 0/6.3 mm fraction; no recycled fine aggregates are included in concrete mixes. <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=precast%20concrete%20blocks" title=" precast concrete blocks"> precast concrete blocks</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20aggregates" title=" recycled aggregates"> recycled aggregates</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20glass" title=" recycled glass"> recycled glass</a> </p> <a href="https://publications.waset.org/abstracts/16126/masonry-blocks-with-recycled-aggregates-and-recycled-glass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16126.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">558</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">414</span> Surface Modification of Polycarbonate Substrates via Direct Fluorination to Promote the Staining with Methylene Blue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haruka%20Kaji">Haruka Kaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Ho%20Kim"> Jae-Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Yonezawa%20Susumu"> Yonezawa Susumu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The surface of polycarbonate (PC) was modified with fluorine gas at 25℃ and 10-380 Torr for one h. The surface roughness of the fluorinated PC samples was approximately five times larger than that (1.2 nm) of the untreated thing. The results of Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy showed that the bonds (e.g., -C=O and C-Hx) derived from raw PC decreased and were converted into fluorinated bonds (e.g., -CFx) after surface fluorination. These fluorinated bonds showed higher electronegativity according to the zeta potential results. Fluorinated PC could be strained with the methylene blue basic dye because of the increased surface roughness and the negatively charged surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dyeable%20layer" title="dyeable layer">dyeable layer</a>, <a href="https://publications.waset.org/abstracts/search?q=polycarbonate" title=" polycarbonate"> polycarbonate</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20fluorination" title=" surface fluorination"> surface fluorination</a>, <a href="https://publications.waset.org/abstracts/search?q=zeta%20potential" title=" zeta potential"> zeta potential</a> </p> <a href="https://publications.waset.org/abstracts/152870/surface-modification-of-polycarbonate-substrates-via-direct-fluorination-to-promote-the-staining-with-methylene-blue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152870.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">180</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">413</span> Analysis of Possibilities for Using Recycled Concrete Aggregate in Concrete Pavement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Pernicova">R.

Percentages of replacement are 0–25% and 50% of aggregates with fine waste glass to produce concrete and percentage of replacement of 100% to produce mortar. As a result of the conducted study, the slump flow increased with the increase of recycled glass content. On the other hand, the compressive strength and tensile strength of recycled glass mixtures were decreased with the increase in the recycled glass content. The results showed that recycled glass aggregate can successfully be used with limited level for producing concrete.

Recycled concrete was obtained by replacing natural aggregates (NA) with recycled concrete aggregate (RCA) and recycled asphalt pavement (RAP) with replacement levels of 20%, 40%, 60%, 80%, and 100% by the total weight of NA. In addition, RCA and RAP were incorporated in the same mixes with replacement levels of (1) 20% RCA and 80% RAP; (2) 40% RCA and 60% RAP; (3) 60% RCA and 40% RAP; and (4) 80% RCA and 20% RAP. A comparison between the experimental capacities and the theoretically predicted values according to Eurocode 4 (EC4) was made as well. Results proved that the ultimate capacity of composite beams decreased with the increase of recycled aggregate (RA) percentage and EC4 was conservative in predicting the ultimate capacity of composite beams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexure" title="flexure">flexure</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20gauge" title=" light gauge"> light gauge</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20asphalt%20pavement" title=" recycled asphalt pavement"> recycled asphalt pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20concrete%20aggregate" title=" recycled concrete aggregate"> recycled concrete aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20tube" title=" steel tube"> steel tube</a> </p> <a href="https://publications.waset.org/abstracts/125387/flexural-behavior-of-light-gauge-steel-box-sections-filled-with-normal-and-recycled-aggregates-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125387.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">199</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">410</span> Effect of Depressurization Rate in Batch Foaming of Porous Microcellular Polycarbonate on Microstructure Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indrajeet%20Singh">Indrajeet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhishek%20Gandhi"> Abhishek Gandhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Smita%20Mohanty"> Smita Mohanty</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Nayak"> S.

The depressurization rate considered in this study were 0.5, 0.05, 0.01 and 0.005 MPa/sec and the physical blowing agent utilized was carbon dioxide owing to its high solubility in polycarbonate at room temperature. The study was performed on two distinct saturation pressures, i.e., 3 MPa and 6 MPa to understand if saturation pressure has any effects on it. It is reported that with increase in depressurization rate, a higher amount of thermodynamic instability was induced which resulted in generation of larger number of smaller sized cells. This article puts forward an understanding of how depressurization rate control could be well exploited during the batch foaming process to develop high quality microcellular foamed products with exceedingly well controlled cell size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=depressurization" title="depressurization">depressurization</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20polymer" title=" porous polymer"> porous polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=foaming" title=" foaming"> foaming</a>, <a href="https://publications.waset.org/abstracts/search?q=microcellular" title=" microcellular"> microcellular</a> </p> <a href="https://publications.waset.org/abstracts/93891/effect-of-depressurization-rate-in-batch-foaming-of-porous-microcellular-polycarbonate-on-microstructure-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93891.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">258</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">409</span> Fire Characteristic of Commercial Retardant Flame Polycarbonate under Different Oxygen Concentration: Ignition Time and Heat Blockage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xuelin%20Zhang">Xuelin Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shouxiang%20Lu"> Shouxiang Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Changhai%20Li"> Changhai Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The commercial retardant flame polycarbonate samples as the main high speed train interior carriage material with different thicknesses were investigated in Fire Propagation Apparatus with different external heat fluxes under different oxygen concentration from 12% to 40% to study the fire characteristics and quantitatively analyze the ignition time, mass loss rate and heat blockage. The additives of commercial retardant flame polycarbonate were intumescent and maintained a steady height before ignition when heated. The results showed the transformed ignition time (1/t_ig)ⁿ increased linearly with external flux under different oxygen concentration after deducting the heat blockage due to pyrolysis products, the mass loss rate was taken on linearly with external heat fluxes and the slop of the fitting line for mass loss rate and external heat fluxes decreased with the enhanced oxygen concentration and the heat blockage independent on external heat fluxes rose with oxygen concentration increasing. The inquired data as the input of the fire simulation model was the most important to be used to evaluate the fire risk of commercial retardant flame polycarbonate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ignition%20time" title="ignition time">ignition time</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20loss%20rate" title=" mass loss rate"> mass loss rate</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20blockage" title=" heat blockage"> heat blockage</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20characteristic" title=" fire characteristic"> fire characteristic</a> </p> <a href="https://publications.waset.org/abstracts/74727/fire-characteristic-of-commercial-retardant-flame-polycarbonate-under-different-oxygen-concentration-ignition-time-and-heat-blockage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74727.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">282</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">408</span> Light Weight Mortars Produced from Recycled Foam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siwat%20Kamonkunanon">Siwat Kamonkunanon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents results of an experimental study on the use of recycled foam with cement-based mixtures to produce light weight mortar.

This study aimed to secure the performance of asphalt concrete mixture by developing recycled-modified asphalt using recycled basalt aggregate from the Jeju area. The strength of the basalt aggregate from the Jeju area used in this study was similar to that of general aggregate, while the specific surface area was larger due to the development of pores. Modified asphalt was developed using a general aggregate-recycled aggregate ratio of 7:3, and the results indicated that the Marshall stability increased by 27% compared to that of asphalt concrete mixture using only general aggregate, and the flow values showed similar levels. Also, the indirect tensile strength increased by 79%, and the toughness increased by more than 100%. In addition, the TSR for examining moisture resistance was 0.95 indicating that the reduction in the indirect tensile strength due to moisture was very low (5% level), and the developed recycled-modified asphalt could satisfy all the quality standards of asphalt concrete mixture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphalt%20concrete%20mixture" title="asphalt concrete mixture">asphalt concrete mixture</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20grade" title=" performance grade"> performance grade</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20basalt%20aggregate" title=" recycled basalt aggregate"> recycled basalt aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled-modified%20asphalt" title=" recycled-modified asphalt"> recycled-modified asphalt</a> </p> <a href="https://publications.waset.org/abstracts/39062/development-of-recycled-modified-asphalt-using-basalt-aggregate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39062.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">358</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">406</span> Recycling of Aggregates from Construction Demolition Wastes in Concrete: Study of Physical and Mechanical Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Saidi">M.

Mortars were elaborated with recycled fine aggregate (0/5mm) and concretes were manufactured using recycled coarse aggregates (5/12.5 mm and 12.5/20 mm). First, a study of the mortars was conducted to determine the effectiveness of adjuvant polycarboxylate superplasticizer on the workability of these and their action deflocculating of the fine recycled sand. The rheological behavior of mortars based on fine aggregate recycled was characterized. The results confirm that the mortars composed of different fractions of recycled sand (0/5) have a better mechanical properties (compressive and flexural strength) compared to normal mortar. Also, the mechanical strengths of concretes made with recycled aggregates (5/12.5 mm and 12.5/20 mm), are comparable to those of conventional concrete with conventional aggregates, provided that the implementation can be improved by the addition of a superplasticizer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demolition%20wastes" title="demolition wastes">demolition wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20coarse%20aggregate" title=" recycled coarse aggregate"> recycled coarse aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=workability" title=" workability"> workability</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20strength" title=" mechanical strength"> mechanical strength</a>, <a href="https://publications.waset.org/abstracts/search?q=porosity%2Fwater%20absorption" title=" porosity/water absorption"> porosity/water absorption</a> </p> <a href="https://publications.waset.org/abstracts/14876/recycling-of-aggregates-from-construction-demolition-wastes-in-concrete-study-of-physical-and-mechanical-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14876.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">338</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">405</span> Microstructural Properties of the Interfacial Transition Zone and Strength Development of Concrete Incorporating Recycled Concrete Aggregate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Boudali">S.

Crushed concrete was sieved to powder fine recycled aggregate (PFRA) less than 80 &micro;m and coarse recycled aggregates (CRA). Physical, mechanical, and microstructural properties for PFRA and CRA were evaluated. The effect of the additional rates of PFRA and CRA on strength development of recycled aggregate concrete (RAC) was investigated. Additionally, the characteristics of interfacial transition zone (ITZ) between cement paste and recycled aggregate were also examined. Results show that concrete mixtures made with 100% of CRA and 40% PFRA exhibited similar performance to that of the control mixture prepared with 100% natural aggregate (NA) and 40% natural pozzolan (NP). Moreover, concrete mixture incorporating recycled aggregate exhibited a slightly higher later compressive strength than that of the concrete with NA. This was confirmed by the very dense microstructure for concrete mixture incorporating recycled concrete aggregates compared to that of conventional concrete mixture. <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=recycled%20concrete%20aggregates" title=" recycled concrete aggregates"> recycled concrete aggregates</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20transition%20zone" title=" interfacial transition zone"> interfacial transition zone</a>, <a href="https://publications.waset.org/abstracts/search?q=powder%20fine%20recycled%20aggregate" title=" powder fine recycled aggregate"> powder fine recycled aggregate</a> </p> <a href="https://publications.waset.org/abstracts/75148/microstructural-properties-of-the-interfacial-transition-zone-and-strength-development-of-concrete-incorporating-recycled-concrete-aggregate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75148.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">340</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">404</span> Durability Aspects of Recycled Aggregate Concrete: An Experimental Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Smitha%20Yadav">Smitha Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=Snehal%20Pathak"> Snehal Pathak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aggregate compositions in the construction and demolition (C&amp;D) waste have potential to replace normal aggregates.

At the same time, the world produces a large amount of construction waste each year. Waste concrete is processed and treated, and the recycled aggregate is used to make pervious concrete, which enables the construction waste to be recycled. Pervious concrete has many advantages such as permeability to water, protection of water resources, and so on. This paper tests the recycled aggregate obtained by crushing high-strength waste concrete (TOU) and low-strength waste concrete (PU), and analyzes the effect of porosity, amount of cement, mineral admixture and recycled aggregate on the strength of permeable concrete. The porosity is inversely proportional to the strength, and the amount of cement used is proportional to the strength. The mineral admixture can effectively improve the workability of the mixture. The quality of recycled aggregates had a significant effect on strength. Compared with concrete using &quot;PU&quot; aggregates, the strength of 7d and 28d concrete using &quot;TOU&quot; aggregates increased by 69.0% and 73.3%, respectively. Therefore, the quality of recycled aggregates should be strictly controlled during production, and the mix ratio should be designed according to different use environments and usage requirements. This test prepared a recycled aggregate permeable concrete with a compressive strength of 35.8 MPa, which can be used for light load roads and provides a reference for engineering applications. <p class="card-text"><strong>Keywords:</strong> <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=permeable%20concrete" title=" permeable concrete"> permeable concrete</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=permeability" title=" permeability"> permeability</a> </p> <a href="https://publications.waset.org/abstracts/85903/experimental-study-on-recycled-aggregate-pervious-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85903.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">224</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">400</span> Effect of Concrete Waste Quality on the Compressive Strength of Recycled Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kebaili%20Bachir">Kebaili Bachir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The reuse of concrete waste as a secondary aggregate could be an efficient solution for sustainable development and long-term environmental protection. The variable nature of waste concrete, with various compressive strengths, can have a negative effect on the final compressive strength of recycled concrete. Accordingly, an experimental test programme was developed to evaluate the effect of parent concrete qualities on the performance of recycled concrete. Three grades with different compressive strengths 10MPa, 20MPa, and 30MPa were considered in the study; moreover, an unknown compressive strength was introduced as well. The trial mixes used 40% secondary aggregates (both course and fine) and 60% of natural aggregates. The compressive strength of the test concrete decrease between 15 and 25% compared to normal concrete with no secondary aggregates. This work proves that the strength properties of the parent concrete have a limited effect on the compressive strength of recycled concrete. Low compressive strength parent concrete when crushed generate a high percentage of recycled coarse aggregates with the less attached mortar and give the same compressive strength as an excellent parent concrete. However, the decrease in compressive strength can be mitigated by increasing the cement content 4% by weight of recycled aggregates used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive" title="compressive">compressive</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled" title=" recycled"> recycled</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/86475/effect-of-concrete-waste-quality-on-the-compressive-strength-of-recycled-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86475.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">399</span> Substitution of Natural Aggregates by Crushed Concrete Waste in Concrete Products Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jozef%20Junak">Jozef Junak</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadezda%20Stevulova"> Nadezda Stevulova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is aimed to the use of different types of industrial wastes in concrete production.

The lowest strength after 28 days of hardening (27.42 MPa) was obtained for sample consisting of recycled concrete in proportion of 40% for 4/8 fraction and 100% for 8/16 fraction of recycled concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recycled%20concrete%20aggregate" title="recycled concrete aggregate">recycled concrete aggregate</a>, <a href="https://publications.waset.org/abstracts/search?q=re-use" title=" re-use"> re-use</a>, <a href="https://publications.waset.org/abstracts/search?q=workability" title=" workability"> workability</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a> </p> <a href="https://publications.waset.org/abstracts/28665/substitution-of-natural-aggregates-by-crushed-concrete-waste-in-concrete-products-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28665.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">371</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">398</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">397</span> Investigating the Properties of Asphalt Concrete Containing Recycled Fillers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Taherkhani">Hasan Taherkhani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Increasingly accumulation of the solid waste materials has become a major environmental problem of communities. In addition to the protection of environment, the recycling and reusing of the waste materials are financially beneficial. Waste materials can be used in highway construction. This study aimed to investigate the applicability of recycled concrete, asphalt and steel slag powder, as a replacement of the primary mineral filler in asphalt concrete has been investigated. The primary natural siliceous aggregate filler, as control, has been replaced with the secondary recycled concrete, asphalt and steel slag powders, and some engineering properties of the mixtures have been evaluated. Marshal Stability, flow, indirect tensile strength, moisture damage, static creep and volumetric properties of the mixtures have been evaluated. The results show that, the Marshal Stability of the mixtures containing recycled powders is higher than that of the control mixture. The flow of the mixtures containing recycled steel slag is lower, and that of the mixtures containing recycled asphalt and cement concrete powder is found to be higher than that of the control mixture. It is also found that the resistance against moisture damage and permanent deformation of the mixture can be improved by replacing the natural filler with the recycled powders. The volumetric properties of the mixtures are not significantly influenced by replacing the natural filler with the recycled powders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=filler" title="filler">filler</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20slag" title=" steel slag"> steel slag</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20concrete" title=" recycled concrete"> recycled concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20asphalt%20concrete" title=" recycled asphalt concrete"> recycled asphalt concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20strength" title=" tensile strength"> tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture%20damage" title=" moisture damage"> moisture damage</a>, <a href="https://publications.waset.org/abstracts/search?q=creep" title=" creep"> creep</a> </p> <a href="https://publications.waset.org/abstracts/71186/investigating-the-properties-of-asphalt-concrete-containing-recycled-fillers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71186.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">277</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">396</span> Use of Recycled Aggregates in Current Concretes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Krizova">K.

To promote sustainable development, this review article evaluates the feasibility of using recycled concrete in construction projects from an economic and environmental perspective. The results show that making concrete using recycled concrete is a suitable strategy for sustainable development. A complete examination of the physical and chemical properties of these recycled materials also provides important information about their suitability for use in the construction industry. Most of the studies do not show surprising results of the compressive or bending strength of these materials, and only the aspect of sustainable development of these materials is of interest. Their application can be investigated more in masonry and joinery works, but among them, some studies sometimes obtained more compressive and bending strength than the control sample, which can be used in concrete structures. Most of the cases introduced and discussed in this study can be implemented and help the country and the people of Iran preserve the environment and discuss sustainable development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20recycling" title="environmental recycling">environmental recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20materials" title=" recycled materials"> recycled materials</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20management" title=" construction management"> construction management</a> </p> <a href="https://publications.waset.org/abstracts/192244/engineering-review-of-recycled-concrete-production-for-structural-and-non-structural-applications-green-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192244.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">27</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">394</span> Stabilization of Fly Ash Slope Using Plastic Recycled Polymer and Finite Element Analysis Using Plaxis 3D</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tushar%20Vasant%20Salunkhe">Tushar Vasant Salunkhe</a>, <a href="https://publications.waset.org/abstracts/search?q=Sariput%20M.%20Nawghare"> Sariput M.

Composites of iPP/3, 7and 10 wt% of solid and hollow recycled PET fibers were prepared by batched melt mixing in a Brabender. The incorporation of solid recycled-PET fibers in isotactic polypropylene increase Young’s modulus of iPP relatively, meanwhile it increased proportionally with hollow fibers content. An improvement of the storage modulus, and a shift up in glass transition temperatures of hollow fibers/iPP composites was determined by DMA results. The morphology of composites was determined by scanning electron microscope (SEM) and optical polarized microscopy (OM) showing a good dispersion of the hollow fibers. Also, their flexible aspect (folding, bending) was observed. But, one weak interaction between the polymer/fibers phases was shown. Polymers can be effectively reinforced with short hollow recycled PET fibers due to their characteristics like recyclability, lightweight and the flexible aspect, which allows the absorbance of the energy of a striker with a minimum damage of the matrix. Aiming to improve the affinity matrix–recycled hollow PET fibers, it is suggested the addition of compatibilizers, as maleic anhydride. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isotactic%20polypropylene" title="isotactic polypropylene">isotactic polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=hollow%20recycled%20PET%20fibers" title=" hollow recycled PET fibers"> hollow recycled PET fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20recycled-PET%20fibers" title=" solid recycled-PET fibers"> solid recycled-PET fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20fiber" title=" short fiber"> short fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=scanning%20electron%20microscope" title=" scanning electron microscope"> scanning electron microscope</a> </p> <a href="https://publications.waset.org/abstracts/87527/effect-of-hollow-and-solid-recycled-poly-fibers-on-the-mechanical-and-morphological-properties-of-short-fiber-reinforced-polypropylene-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87527.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">276</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">391</span> The Efferent of Different Levels of Recycled Soybean Oil(RSO) on Growth and Performance of Broilers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Babak%20Asadi">Seyed Babak Asadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this experiment the effect of recycled soybean oil (RSO) on the growth and performance carcass of broiler was investigated.

In this regard, 300 one-day-old broilers were selected randomly consisting of five treatments and three replicates(20 chickens per replicate). The chicks were kept in an accumulated manner for the first week, then divided between treatments and kept until they reached the age of 42 days. Body weight at 21 and 42, weight gain, food intake and food conversion ratio in starter (0-21 d), finisher (21-42 d) and overall were measured. At the end of the experiment (42 days-old) 2 chicks from each replicate which had the nearest weight to the average group in their group were selected, slaughtered and different parts of their carcass were weight separately. The result showed that the rate of feed intake and feed conversion coefficient have significantly increased with higher levels of recycled soybean oil. There was not a significant different between experimental groups for liver, heart, intestine and the weight of carcass.

The results show that concrete could be produced by using recycled brick aggregates and reveals that at high temperatures recycled aggregate concrete preformed similar or even better than natural aggregate concrete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20temperature" title="high temperature">high temperature</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=mass%20loss" title=" mass loss"> mass loss</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20brick%20aggregate" title=" recycled brick aggregate"> recycled brick aggregate</a> </p> <a href="https://publications.waset.org/abstracts/37547/effect-of-high-temperature-on-residual-mechanical-and-physical-properties-of-brick-aggregate-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37547.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">245</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">388</span> Procedure for Impact Testing of Fused Recycled Glass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Halley">David Halley</a>, <a href="https://publications.waset.org/abstracts/search?q=Tyra%20Oseng-Rees"> Tyra Oseng-Rees</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Pagano"> Luca Pagano</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20A%20Ferriz-Papi"> Juan A Ferriz-Papi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recycled glass material is made from 100% recycled bottle glass and consumes less energy than re-melt technology. It also uses no additives in the manufacturing process allowing the recycled glass material, in principal, to go back to the recycling stream after end-of-use, contributing to the circular economy with a low ecological impact. The aim of this paper is to investigate the procedure for testing the recycled glass material for impact resistance, so it can be applied to pavements and other surfaces which are at risk of impact during service. A review of different impact test procedures for construction materials was undertaken, comparing methodologies and international standards applied to other materials such as natural stone, ceramics and glass. A drop weight impact testing machine was designed and manufactured in-house to perform these tests. As a case study, samples of the recycled glass material were manufactured with two different thicknesses and tested. The impact energy was calculated theoretically, obtaining results with 5 and 10 J. The results on the material were subsequently discussed. Improvements on the procedure can be made using high speed video technology to calculate velocity just before and immediately after the impact to know the absorbed energy. The initial results obtained in this procedure were positive although repeatability needs to be developed to obtain a correlation of results and finally be able to validate the procedure. The experiment with samples showed the practicality of this procedure and application to the recycled glass material impact testing although further research needs to be developed. <p
