Kaddami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work describes an investigation on the effect of filler metals diameter to weld joint, and low alloy carbon steel A516 Grade 70 is the base metal. Commercially SA516 Grade70 is frequently used for the manufacturing of pressure vessels, boilers and storage tank, etc. In fabrication industry, the hardness of the weld joint is between the important parameters to check, after heat treatment of the weld. Submerged arc welding (SAW) is used with two filler metal diameters, and this solid wire electrode is used for SAW non-alloy and for fine grain steels (SFA 5.17). The different diameters were selected (Ø = 2.4 mm and Ø = 4 mm) to weld two specimens. Both specimens were subjected to the same preparation conditions, heat treatment, macrograph, metallurgy micrograph, and micro-hardness test. Samples show almost similar structure with highest hardness. It is important to indicate that the thickness used in the base metal is 22 mm, and all specifications, preparation and controls were according to the ASME section IX. It was observed that two different filler metal diameters performed on two similar specimens demonstrated that the mechanical property (hardness) increases with decreasing diameter. It means that even the heat treatment has the same effect with the same conditions, the filler metal diameter insures a depth weld penetration and better homogenization. Hence, the SAW welding technique mentioned in the present study is favorable to implicate for the industry using the small filler metal diameter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ASME" title="ASME">ASME</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20metal" title=" base metal"> base metal</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-hardness%20test" title=" micro-hardness test"> micro-hardness test</a>, <a href="https://publications.waset.org/abstracts/search?q=submerged%20arc%20welding" title=" submerged arc welding"> submerged arc welding</a> </p> <a href="https://publications.waset.org/abstracts/96792/effect-of-filler-metal-diameter-on-weld-joint-of-carbon-steel-sa516-gr-70-and-filler-metal-sfa-517-in-submerged-arc-welding-saw" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96792.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">153</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">2678</span> Investigation on Corrosion Behavior of Copper Brazed Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20Aminazad">A.

Copper sheets and tubes (ISODHP) were brazed with four different brazing alloys. Corrosion resistances of the joints were examined by polarization and salt spray tests. The selected fillers consisted of three silver-based brazing alloys (hard solder); AWS-BCu5 BAg8, DINLAg30, and a copper-based filler AWS BCuP2. All the joints were brazed utilizing four different brazing processes including furnace brazing under argon, vacuum, air atmosphere and torch brazing. All of the fillers were used with and without flux. The microstructure of the brazed sheets was examined using both optical and scanning electron microscope (SEM). Hardness and leak tests were carried out on all the brazed tubes. In all three silver brazing alloys selective and galvanic corrosion were observed in filler metals, but in copper phosphor alloys the copper adjacent to the joints were noticeably corroded by pitting method. Microstructure of damaged area showed selective attack of copper lamellae as well. Interfacial attack was observed along boundaries as well as copper attack within the filler metal itself. It was found that the samples brazed with BAg5 filler metal using vacuum furnace show a higher resistance to corrosion. They also have a good ductility in the brazed zone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=copper" title="copper">copper</a>, <a href="https://publications.waset.org/abstracts/search?q=brazing" title=" brazing"> brazing</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=filler%20metal" title=" filler metal"> filler metal</a> </p> <a href="https://publications.waset.org/abstracts/24596/investigation-on-corrosion-behavior-of-copper-brazed-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24596.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">470</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">2677</span> Comparison of Mechanical Property of UNS C12200Joints Brazed by (Cu&Ag) Based Filler Metals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Elhatmi">Ali Elhatmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Elshbo"> Mustafa Elshbo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussin%20Alosta"> Hussin Alosta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study the coper tube witch used in medical applications was brazed by Copper, Zink and Silver alloys, using BCuP2, RBCuZnAl and BAg2 filler metals.

Ability of joining process to assembly these different material combinations is always a challenge to the designer. In this study, 0.6 mm thick 6061-T6 and 2 mm thick 5182-O were robot CMT welded using ER5356 and ER4043 filler metals. The thermal effect of welding resulted in a loss of hardness in the 6061 HAZ. Joints welded by ER5356 filler metal were much higher in fracture load than joints welded by ER4043 and the elongation of joints welded by ER5356 was almost double its corresponding joints welded by ER4043 filler. Owing to the big difference in formability and thickness of base metals, the fracture in forming test occurred in the softened 6061 HAZ out from the weld centerline. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum" title="aluminum">aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=CMT" title=" CMT"> CMT</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical" title=" mechanical"> mechanical</a>, <a href="https://publications.waset.org/abstracts/search?q=welding" title=" welding "> welding </a> </p> <a href="https://publications.waset.org/abstracts/7450/cold-metal-transfer-welding-of-dissimilar-thickness-6061-t6-to-5182-o-aluminum-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7450.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">231</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">2675</span> Effect of Filler Size and Shape on Positive Temperature Coefficient Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20Asare">Eric Asare</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamie%20Evans"> Jamie Evans</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Newton"> Mark Newton</a>, <a href="https://publications.waset.org/abstracts/search?q=Emiliano%20Bilotti"> Emiliano Bilotti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two types of filler shapes (sphere and flakes) and three different sizes are employed to study the size effect on PTC. The composite is prepared using a mini-extruder with high-density polyethylene (HDPE) as the matrix. A computer modelling is used to fit the experimental results. The percolation threshold decreases with decreasing filler size and this was observed for both the spherical particles as well as the flakes. This was caused by the decrease in interparticle distance with decreasing filler size. The 100 µm particles showed a larger PTC intensity compared to the 5 µm particles for the metal coated glass sphere and flake. The small particles have a large surface area and agglomeration and this makes it difficult for the conductive network to e disturbed. Increasing the filler content decreased the PTC intensity and this is due to an increase in the conductive network within the polymer matrix hence more energy is needed to disrupt the network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=positive%20temperature%20coefficient%20%28PTC%29%20effect" title="positive temperature coefficient (PTC) effect">positive temperature coefficient (PTC) effect</a>, <a href="https://publications.waset.org/abstracts/search?q=conductive%20polymer%20composite%20%28CPC%29" title=" conductive polymer composite (CPC)"> conductive polymer composite (CPC)</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title=" electrical conductivity"> electrical conductivity</a> </p> <a href="https://publications.waset.org/abstracts/19230/effect-of-filler-size-and-shape-on-positive-temperature-coefficient-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19230.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">427</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">2674</span> The Electrical Properties of Polyester Materials as Outdoor Insulators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20M.%20EL-Sharkawy">R.

Cylindrical of polyester composite samples (with different lengths) have been prepared after incorporated with different concentration of inorganic filler e.g. Magnesium Hydroxide [Mg(OH)2] to improve the electrical and thermal properties in addition to maximize surface flashover voltage and decrease tracking phenomena. Results showed that flashover voltage reaches to 46 kV for samples without filler and 52.6 kV for samples containing 40% of [Mg(OH)2] filler in dry condition. A comparison between different concentrations of filler under various environmental conditions (dry and contaminated conditions) showed higher flashover voltage values for samples containing filler with ratio 40% [Mg(OH)2] and length 3cm than that of samples containing filler [Mg(OH)2] with ratios 20%, 30% and lengths 0.5cm, 1cm, 2cm and 2.5cm. Flashover voltage decreases by adding [Mg(OH)2] filler for polyester samples under ultra-violet condition; as the ratio of filler increases, the value of flashover voltage decreases Also, in this study, the effect of thermal performance with respect to surface of the sample under test have been investigated in details. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flashover%20voltage" title="flashover voltage">flashover voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=filler" title=" filler"> filler</a>, <a href="https://publications.waset.org/abstracts/search?q=polymers" title=" polymers"> polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=ultra-violet%20radiation" title=" ultra-violet radiation"> ultra-violet radiation</a> </p> <a href="https://publications.waset.org/abstracts/40599/the-electrical-properties-of-polyester-materials-as-outdoor-insulators" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40599.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">315</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">2673</span> Development of High Strength Filler Consumables by Means of Calculations and Microstructural Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Holly">S.

In the scope of the development of a metal-cored wire with the target tensile strength of 1150 MPa and acceptable impact toughness, thermodynamic and kinetic calculations via MatCalc were used to reduce the experimental work and the resources required. Micro alloying elements were used to reach the high strength as an alternative approach compared to the conventional solid solution hardening. In order to understand the influence of different micro alloying elements in more detail, the influence of different elements on the precipitation behavior in the weld metal was evaluated. Investigations of the microstructure were made via atom probe and EBSD to understand the effect of micro alloying elements. The calculated results are in accordance with the results obtained by experiments and can be explained by the microstructural investigations. On the example of aluminium, the approach is exemplified and clarifies the efficient way of development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alloy%20development" title="alloy development">alloy development</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20strength%20steel" title=" high strength steel"> high strength steel</a>, <a href="https://publications.waset.org/abstracts/search?q=MatCalc" title=" MatCalc"> MatCalc</a>, <a href="https://publications.waset.org/abstracts/search?q=metal-cored%20wire" title=" metal-cored wire"> metal-cored wire</a> </p> <a href="https://publications.waset.org/abstracts/58448/development-of-high-strength-filler-consumables-by-means-of-calculations-and-microstructural-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58448.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">237</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">2672</span> Study of Ladle Furnace Slag as Mineral Filler in Asphalt Concrete with Electric Arc Furnace Slag</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20J.%20Wang">W.

First of all, the engineering properties of the ladle furnace slag and lime were compared, and then the mineral filler was mixed with bitumen to form the asphalt cement mastics in order to analyze the influence of the ladle furnace slag on the properties of asphalt cement mastics, and lastly, the mineral filler was used in the EAF asphalt concrete to analyze its feasibility of using ladle furnace slag as a mineral filler. The study result shows that the ladle furnace slag and the lime have no obvious difference in their physical properties, and from the energy dispersive spectrometer (EDS) test results, we know that the lime and the ladle furnace slag have similar elemental composition, but the Ca found in the ladle furnace slag belongs to CaO, and the lime belongs to CaCO3, therefore the ladle furnace slag has the property of expansion. According to the test results, the viscosity of asphalt cement mastics will increase with the increase in the use of mineral filler. Since the ladle furnace slag has more CaO content, the viscosity of the asphalt cement mastics with ladle furnace slag will increase more than using lime as mineral filler in the asphalt cement mastics, and the use of ladle furnace slag only needs to be 2% in order to achieve the effect of anti-peeling which is 6% for lime. From the related test results of EAF asphalt concrete, it is known that the maximum stability value can be obtained when the use of mineral filler is about 5%. When the ladle furnace slag is used as the mineral filler, it can improve the stiffness, indirect tension strength, spalling resistance, and thermal insulation of EAF asphalt concrete, which also indicates that using the ladle furnace slag as the mineral filler of bitumen can help to improve the durability of the asphalt pavement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ladle%20furnace%20slag" title="ladle furnace slag">ladle furnace slag</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20filler" title=" mineral filler"> mineral filler</a>, <a href="https://publications.waset.org/abstracts/search?q=asphalt%20cement%20mastics" title=" asphalt cement mastics"> asphalt cement mastics</a>, <a href="https://publications.waset.org/abstracts/search?q=EAF%20asphalt%20concrete" title=" EAF asphalt concrete"> EAF asphalt concrete</a> </p> <a href="https://publications.waset.org/abstracts/170204/study-of-ladle-furnace-slag-as-mineral-filler-in-asphalt-concrete-with-electric-arc-furnace-slag" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170204.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2671</span> The Influence of Brazing Method on Corrosion Behavior of Brazed Aluminum Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Ghasim-akbari">F.

For many applications they have to be brazed to each other. The brazed joints, in many cases, are encountered with corrosive medias. This paper reports a part of a work to investigate the corrosion behavior of brazed Al6061 using Al4047 as filler metal with and without the use of flux to discover the effect of different brazing atmospheres. The samples brazed under air, vacuum, argon, and hydrogen atmospheres. The interfacial area of the joints was examined to ensure being free of any defects. The sides of each test piece were covered with insulator and the surface of the joint was encountered to polarization test. The results revealed a significant difference of corrosion resistance. The samples that brazed under argon and hydrogen atmospheres had better corrosion resistance than other samples. Microstructure of the corroded joints revealed that the amount of the filler metal is a critical parameter on corrosion resistance of the joints. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brazing" title="brazing">brazing</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20behavior" title=" corrosion behavior"> corrosion behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=Al6061" title=" Al6061"> Al6061</a>, <a href="https://publications.waset.org/abstracts/search?q=polarization" title=" polarization"> polarization</a> </p> <a href="https://publications.waset.org/abstracts/24594/the-influence-of-brazing-method-on-corrosion-behavior-of-brazed-aluminum-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24594.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">498</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">2670</span> Synthesis and Characterization of Amino-Functionalized Polystyrene Nanoparticles as Reactive Filler</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yaseen%20Elhebshi">Yaseen Elhebshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulkareem%20Hamid"> Abdulkareem Hamid</a>, <a href="https://publications.waset.org/abstracts/search?q=Nureddin%20Bin%20Issa"> Nureddin Bin Issa</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaonong%20Chen"> Xiaonong Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A convenient method of preparing ultrafine polystyrene latex nano-particles with amino groups on the surface is developed.

Thermal studies were conducted, as it understanding is vital for preliminary development of new polymeric systems. Thermal analysis of nano composite was conducted using thermo gravimetric analysis (TGA), and differential scanning calorimetry (DSC). Major finding of TGA indicated two main stages of degradation process found at (350 ± 25 oC) and (480 ± 25 oC) respectively. Nano metal filler expressed better fire resistance as it stand over high degree of temperature. Furthermore, DSC analysis provided a stable glass temperature around 51 (±1 oC) and captured double melting point at 84 (±2 oC) and 108 (±2 oC). This binary melting point reflects the modification of nano filler to the polymer matrix forming melting crystals of folded and extended chain. The percent crystallinity of the samples grew vividly with increasing filler content. Overall, increasing the filler loading improved the degradation temperature and weight loss evidently and a better process and phase stability was captured in DSC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title="thermal properties">thermal properties</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20MH" title=" nano MH"> nano MH</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20particles" title=" nano particles"> nano particles</a>, <a href="https://publications.waset.org/abstracts/search?q=cable%20and%20wire" title=" cable and wire"> cable and wire</a>, <a href="https://publications.waset.org/abstracts/search?q=LDPE%2FEVA" title=" LDPE/EVA"> LDPE/EVA</a> </p> <a href="https://publications.waset.org/abstracts/17357/the-thermal-properties-of-nano-magnesium-hydroxide-blended-with-ldpeevairganox1010-for-insulator-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17357.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">451</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">2668</span> Exploring the Efficacy of Nitroglycerin in Filler-Induced Facial Skin Ischemia: A Narrative ‎Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Feily">Amir Feily</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazhir%20Shahmoradi%20Akram"> Hazhir Shahmoradi Akram</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Ghaedi"> Mojtaba Ghaedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Javdani"> Farshid Javdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Naser%20Hatami"> Naser Hatami</a>, <a href="https://publications.waset.org/abstracts/search?q=Navid%20Kalani"> Navid Kalani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Zarenezhad"> Mohammad Zarenezhad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Filler-induced facial skin ischemia is a potential complication of dermal filler injections that can result in tissue damage and necrosis. Nitroglycerin has been suggested as a treatment option due to its vasodilatory effects, but its efficacy in this context is unclear. Methods: A narrative review was conducted to examine the available evidence on the efficacy of nitroglycerin in filler-induced facial skin ischemia. Relevant studies were identified through a search of electronic databases and manual searching of reference lists. Results: The review found limited evidence supporting the efficacy of nitroglycerin in this context. While there were case reports where the combination of nitroglycerin and hyaluronidase was successful in treating filler-induced facial skin ischemia, there was only one case report where nitroglycerin alone was successful. Furthermore, a rat model did not demonstrate any benefits of nitroglycerin and showed harmful results. Conclusion: The evidence regarding the efficacy of nitroglycerin in filler-induced facial skin ischemia is inconclusive and seems to be against its application. Further research is needed to determine the effectiveness of nitroglycerin alone and in combination with other treatments for this condition. Clinicians should consider limited evidence bases when deciding on treatment options for patients with filler-induced facial skin ischemia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nitroglycerin" title="nitroglycerin">nitroglycerin</a>, <a href="https://publications.waset.org/abstracts/search?q=facial" title=" facial"> facial</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20ischemia" title=" skin ischemia"> skin ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=fillers" title=" fillers"> fillers</a>, <a href="https://publications.waset.org/abstracts/search?q=efficacy" title=" efficacy"> efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative%20review" title=" narrative review"> narrative review</a> </p> <a href="https://publications.waset.org/abstracts/171621/exploring-the-efficacy-of-nitroglycerin-in-filler-induced-facial-skin-ischemia-a-narrative-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171621.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">2667</span> Mathematical Analysis of Matrix and Filler Formulation in Composite Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusegun%20A.%20Afolabi">Olusegun A.

Composite material is the combination of separate materials with different properties to form a single material having different properties from the parent materials. Material composition and combination is an important aspect of composite material. The focus of this study is to provide insight into an easy way of calculating the compositions and formulations of constituent materials that make up any composite material. The compositions of the matrix and filler used for fabricating composite materials are taken into consideration. From the composite fabricated, data can be collected and analyzed based on the test and characterizations such as tensile, flexural, compression, impact, hardness, etc. Also, the densities of the matrix and the filler with regard to their constituent materials are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20material" title="composite material">composite material</a>, <a href="https://publications.waset.org/abstracts/search?q=density" title=" density"> density</a>, <a href="https://publications.waset.org/abstracts/search?q=filler" title=" filler"> filler</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix" title=" matrix"> matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=percentage%20weight" title=" percentage weight"> percentage weight</a>, <a href="https://publications.waset.org/abstracts/search?q=volume%20fraction" title=" volume fraction"> volume fraction</a> </p> <a href="https://publications.waset.org/abstracts/182436/mathematical-analysis-of-matrix-and-filler-formulation-in-composite-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182436.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">67</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">2666</span> Development of Mixed Matrix Membranes by Using NH₂-Functionalized UiO-66 and [APTMS][AC] Ionic Liquid for the Separation of CO₂</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hafiza%20Mamoona%20Khalid">Hafiza Mamoona Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Afshan%20Mujahid"> Afshan Mujahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Asif%20Ali"> Asif Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Asim%20Laeeq%20Khan"> Asim Laeeq Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmood%20Saleem"> Mahmood Saleem</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20M.%20Santos"> Rafael M.

Mixed matrix membranes (MMMs), which are fabricated by incorporating the beneﬁcial properties of highly selective inorganic ﬁllers into a polymer matrix, have exhibited signiﬁcant progress and the ability to enhance the performance of a membrane for gas separation. In this research, an amine-based ionic liquid (IL) [APTMS][AC] was prepared, which has greater CO₂ afﬁnity and greater solubility due to its amine moiety. The metal–organic framework (MOF) UiO-66 with a multidimensional crystalline structure was used as a ﬁller due to its appropriate porosity and tunable properties, and it was functionalized with NH₂. MOFs were further modiﬁed with an IL to prepare UiO-66@IL and UiO-66-NH₂@IL, and MMMs incorporating each MOF were fabricated with the polymer Pebax-1657. All the prepared membranes and MOFs were characterized to predict their separation efﬁciency. Several characterization techniques, namely, FTIR spectroscopy, XRD, and SEM, were used to successfully synthesize UiO-66@IL and UiO-66-NH₂@IL composites and conﬁrmed proper dispersion and excellent polymer‒ ﬁller compatibility at ﬁller loadings ranging from 0 to 30 wt.%. The separation performances were investigated, and the results showed that the incorporation of RTIL with the highly crystalline structure and large surface area of UiO-66 enhanced the separation efﬁciency of the membrane. The permeability of CO₂ for all fabricated membranes continuously increased with increasing ﬁller concentration, wherein the permeability was comparatively high for the UiO-66-NH₂ MMMs. The CO₂/CH₄ selectivity improved by 35%, 54%, and 60%, respectively, for UiO-66@IL, UiO-66-NH₂, and UiO-66-NH₂@IL MMMs compared to simple UiO-66 for CO₂/CH₄ and by 28%, 36%, and 63%, respectively, for CO₂/N₂, with an increase in ﬁller loading in the MMMs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20separation" title="gas separation">gas separation</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20matrix%20membranes" title=" mixed matrix membranes"> mixed matrix membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20sequestration" title=" CO₂ sequestration"> CO₂ sequestration</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20warming" title=" global warming"> global warming</a> </p> <a href="https://publications.waset.org/abstracts/193330/development-of-mixed-matrix-membranes-by-using-nh2-functionalized-uio-66-and-aptmsac-ionic-liquid-for-the-separation-of-co2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193330.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">13</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">2665</span> Thermal Property Improvement of Silica Reinforced Epoxy Composite Specimens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyu%20Sang%20Jo">Hyu Sang Jo</a>, <a href="https://publications.waset.org/abstracts/search?q=Gyo%20Woo%20Lee"> Gyo Woo Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the mechanical and thermal properties of epoxy composites that are reinforced with micrometer-sized silica particles were investigated by using the specimen experiments.

The improvement of thermal stability of the silica-reinforced specimen was confirmed to be within the experimented range, and the smaller silica particle was found to be more effective in delaying the thermal expansion of the specimens.

Different braze gaps, brazing times and forms of braze filler material were tested. It was determined that the melting point depressants B and Si tend to form hard and brittle phases in the joint during the braze cycle. Brittle phases significantly reduce mechanical properties (e. g. tensile strength) of the joint. Therefore, it is important to define optimal process parameters to achieve high strength joints, free of brittle phases. High ultimate tensile strength (UTS) values can be obtained if the joint area is free of brittle phases, which is equivalent to a complete isothermal solidification of the joint. Isothermal solidification takes place only if the concentration of the melting point depressant in the braze filler material of the joint is continuously reduced by diffusion into the base material. For a given brazing temperature, long brazing times and small braze filler material volumes (small braze gaps) are beneficial for isothermal solidification. On the base of the obtained results it can be stated that the form of the braze filler material has an additional influence on the joint quality. Better properties can be achieved by the use of braze-filler-material in form of foil instead of braze-filler-material in form of paste due to a reduced amount of voids and a more homogeneous braze-filler-material-composition in the braze-gap by using foil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diffusion%20brazing" title="diffusion brazing">diffusion brazing</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=superalloy" title=" superalloy"> superalloy</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20strength" title=" tensile strength"> tensile strength</a> </p> <a href="https://publications.waset.org/abstracts/6452/influence-of-brazing-process-parameters-on-the-mechanical-properties-of-nickel-based-superalloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6452.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">363</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">2663</span> Thermal Property of Multi-Walled-Carbon-Nanotube Reinforced Epoxy Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Ye%20Koo">Min Ye Koo</a>, <a href="https://publications.waset.org/abstracts/search?q=Gyo%20Woo%20Lee"> Gyo Woo Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, epoxy composite specimens reinforced with multi-walled carbon nanotube filler were fabricated using shear mixer and ultra-sonication processor.

On the basis of the measured and evaluated properties of the composites, we believe that the simple and time-saving fabrication process used in this study was sufficient to obtain improved properties of the specimens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube%20filler" title="carbon nanotube filler">carbon nanotube filler</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20composite" title=" epoxy composite"> epoxy composite</a>, <a href="https://publications.waset.org/abstracts/search?q=ultra-sonication" title=" ultra-sonication"> ultra-sonication</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20mixer" title=" shear mixer"> shear mixer</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20property" title=" mechanical property"> mechanical property</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20property" title=" thermal property"> thermal property</a> </p> <a href="https://publications.waset.org/abstracts/19913/thermal-property-of-multi-walled-carbon-nanotube-reinforced-epoxy-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19913.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">370</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">2662</span> Evaluation of Vine Stem Waste as a Filler Material for High Density Polyethylene </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Seki">Y.

Vine stem, as an agricultural waste, was used as a filler material for a thermoplastic polymer, high-density polyethylene (HDPE) in this study. Agricultural waste of vine stem was collected from Manisa region, Turkey. Vine stem at different rations was used to reinforce HDPE. The effect of vine stem loading on tensile strength and Young’s modulus of composites were obtained. It was clearly observed that tensile strength and Young’s modulus of HDPE was increased by vine stem loading. Thermal stabilities of composites were obtained by using thermogravimetric analysis. Water absorption behavior of HDPE was improved by loading vine stem into HDPE. The crystallinity index values of neat HDPE and vine stem loaded HDPE composites were investigated byX-ray diffraction analysis. From this study, it was inferred that vine stem, as an agricultural waste, can be used as a filler material for HDPE. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20filler" title="waste filler">waste filler</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20density%20polyethylene" title=" high density polyethylene"> high density polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title=" composite materials"> composite materials</a> </p> <a href="https://publications.waset.org/abstracts/25185/evaluation-of-vine-stem-waste-as-a-filler-material-for-high-density-polyethylene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25185.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">515</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2661</span> Effect of Chemical Modifier on the Properties of Polypropylene (PP) / Coconut Fiber (CF) in Automotive Application </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Shahril">K.

Treated (with chemical modifier) and untreated (without chemical modifier) composites were prepared in the formulation of 10 wt%, 20 wt%, 30 wt%, and 40 wt%. The mechanical testing indicates that composite with 10 wt% of untreated composite has the optimum value of tensile strength, and the composite with chemical modifier shows the tensile strength was increased. By increasing of filler loading, elastic modulus was increased while the elongation at brake was decreased. Meanwhile, the swelling test discerned that the increase of filler loading increased the water absorption of composites and the presence of chemical modifier reduced the equilibrium water absorption percentage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coconut%20fiber" title="coconut fiber">coconut fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene" title=" polypropylene"> polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20acrylic" title=" acid acrylic"> acid acrylic</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20modifier" title=" chemical modifier"> chemical modifier</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a> </p> <a href="https://publications.waset.org/abstracts/14842/effect-of-chemical-modifier-on-the-properties-of-polypropylene-pp-coconut-fiber-cf-in-automotive-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14842.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">461</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">2660</span> Tensile and Flexural Behavior of Particulate Filled/Polymer Matrix Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Alsaadi">M.

The resulting degree of particle dispersion in the polymer matrix was visualized by using scanning electron microscope (SEM). Results from this study showed that the tensile strength increased up to its maximum value at filler content 5 wt% of SSA, FA and SiC. Flexural strength increased with addition of particulate filler up to its maximum value at filler content 5 wt% of SSA and FA while for SiC decreased for all weight fractions gradually. The addition of SSA, FA and SiC fillers resulted in increase of tensile and flexural modulus for all the particulate composites.

The paper presents the influence of ground clay brick filler on the properties of self-compacting lightweight concrete (SCLC). In the manufacture and transport of clay bricks, product damage may occur. The filler was obtained by milling the damaged clay brick and sieved under the 0.04 mm size. The composition of each of SCLC mixture was determined according to the CBI method and compared with EFNARC (European Association) criteria. Self-compacting lightweight concrete has been tested in a fresh (slump flow method, visual assessment of stability, T50 time, V-funnel method, L-box method and J-ring) and hardened state (compressive strengths and dynamic modulus of elasticity). Mixtures with this filler had good results of compressive strength, but in fresh state the mixtures were sticky. All results were analyzed and compared with previous studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CBI%20methods" title="CBI methods">CBI methods</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20clay%20brick" title=" ground clay brick"> ground clay brick</a>, <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20lightweight%20concrete" title=" self-compacting lightweight concrete"> self-compacting lightweight concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20fume" title=" silica fume"> silica fume</a> </p> <a href="https://publications.waset.org/abstracts/85392/effect-of-clay-brick-filler-on-properties-of-self-compacting-lightweight-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85392.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2658</span> An Investigation on MgAl₂O₄ Based Mould System in Investment Casting Titanium Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen%20Yuan">Chen Yuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nick%20Green"> Nick Green</a>, <a href="https://publications.waset.org/abstracts/search?q=Stuart%20Blackburn"> Stuart Blackburn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The investment casting process offers a great freedom of design combined with the economic advantage of near net shape manufacturing. It is widely used for the production of high value precision cast parts in particularly in the aerospace sector. Various combinations of materials have been used to produce the ceramic moulds, but most investment foundries use a silica based binder system in conjunction with fused silica, zircon, and alumino-silicate refractories as both filler and coarse stucco materials. However, in the context of advancing alloy technologies, silica based systems are struggling to keep pace, especially when net-shape casting titanium alloys. Study has shown that the casting of titanium based alloys presents considerable problems, including the extensive interactions between the metal and refractory, and the majority of metal-mould interaction is due to reduction of silica, present as binder and filler phases, by titanium in the molten state. Cleaner, more refractory systems are being devised to accommodate these changes. Although yttria has excellent chemical inertness to titanium alloy, it is not very practical in a production environment combining high material cost, short slurry life, and poor sintering properties. There needs to be a cost effective solution to these issues. With limited options for using pure oxides, in this work, a silica-free magnesia spinel MgAl₂O₄ was used as a primary coat filler and alumina as a binder material to produce facecoat in the investment casting mould. A comparison system was also studied with a fraction of the rare earth oxide Y₂O₃ adding into the filler to increase the inertness. The stability of the MgAl₂O₄/Al₂O₃ and MgAl₂O₄/Y₂O₃/Al₂O₃ slurries was assessed by tests, including pH, viscosity, zeta-potential and plate weight measurement, and mould properties such as friability were also measured. The interaction between the face coat and titanium alloy was studied by both a flash re-melting technique and a centrifugal investment casting method. The interaction products between metal and mould were characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM) and Energy Dispersive X-Ray Spectroscopy (EDS). The depth of the oxygen hardened layer was evaluated by micro hardness measurement. Results reveal that introducing a fraction of Y₂O₃ into magnesia spinel can significantly increase the slurry life and reduce the thickness of hardened layer during centrifugal casting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloy" title="titanium alloy">titanium alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=mould" title=" mould"> mould</a>, <a href="https://publications.waset.org/abstracts/search?q=MgAl%E2%82%82O%E2%82%84" title=" MgAl₂O₄"> MgAl₂O₄</a>, <a href="https://publications.waset.org/abstracts/search?q=Y%E2%82%82O%E2%82%83" title=" Y₂O₃"> Y₂O₃</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=investment%20casting" title=" investment casting"> investment casting</a> </p> <a href="https://publications.waset.org/abstracts/114708/an-investigation-on-mgal2o4-based-mould-system-in-investment-casting-titanium-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114708.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">113</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">2657</span> Investigation of Fusion Zone Microstructures in Plasma Arc Welding of Austenitic Stainless Steel (SS-304L) with Low Carbon Steel (A-36) with or without Filler Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shan-e-Fatima">Shan-e-Fatima</a>, <a href="https://publications.waset.org/abstracts/search?q=Mushtaq%20Khan"> Mushtaq Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Imran%20Hussian"> Syed Imran Hussian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plasma arc welding technology is used for welding SS-304L with A-36.

Fracture toughness of the composites were determined according to ASTM D5045 and Single Edge Notch Bending (SENB) been employed during the test. The effects of alkali treatment were also investigated in this study. The results indicate that the fracture toughness slightly increased as clay loading increased. The highest value of fracture toughness was 0.47 and 1.06 MPa.m1/2 at 5 phr for both types of clay loading. The presence of filler as reinforcement with the matrix indicates the enhancement of composites compared to those without the filler. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20palm%20empty%20fruit%20bunch" title="oil palm empty fruit bunch">oil palm empty fruit bunch</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber" title=" fiber"> fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene" title=" polyethylene"> polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20nanocomposite" title=" polymer nanocomposite"> polymer nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20strength" title=" impact strength"> impact strength</a> </p> <a href="https://publications.waset.org/abstracts/9134/the-role-of-secondary-filler-on-the-fracture-toughness-of-hdpeclay-nanocomposites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9134.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">583</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">2655</span> Permanent Deformation Resistance of Asphalt Mixtures with Red Mud as a Filler</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liseane%20Padilha%20Thives">Liseane Padilha Thives</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayara%20S.%20S.%20Lima"> Mayara S.

The large quantity of red mud generated and inadequately disposed in the environment has motivated researchers to develop methods for reinsertion of this waste into the productive cycle. This work aims to evaluate the resistance to permanent deformation of dense asphalt mixtures with red mud filler. The red mud was characterized by tests of X-ray diffraction, fluorescence, specific mass, laser granulometry, pH and scanning electron microscopy. For the analysis of the influence of the quantity of red mud in the mechanical performance of asphalt mixtures, a total filler content of 7% was established. Asphalt mixtures with 3%, 5% and 7% red mud were produced. A conventional mixture with 7% stone powder filler was used as reference. The asphalt mixtures were evaluated for performance to permanent deformation in the French Rutting Tester (FRT) traffic simulator. The mixture with 5% red mud presented greater resistance to permanent deformation with rutting depth at 30,000 cycles of 3.50%. The asphalt mixtures with red mud presented better performance, with reduction of the rutting of 12.63 to 42.62% in relation to the reference mixture. This study confirmed the viability of reinserting the red mud in the production chain and possible usage in the construction industry. The red mud as filler in asphalt mixtures is a reuse option of this waste and mitigation of the disposal problems, as well as being an environmentally friendly alternative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asphalt%20mixtures" title="asphalt mixtures">asphalt mixtures</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20deformation" title=" permanent deformation"> permanent deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20mud" title=" red mud"> red mud</a>, <a href="https://publications.waset.org/abstracts/search?q=pavements" title=" pavements"> pavements</a> </p> <a href="https://publications.waset.org/abstracts/72325/permanent-deformation-resistance-of-asphalt-mixtures-with-red-mud-as-a-filler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72325.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">289</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">2654</span> Effects of Flame Retardant Nano Bio-Filler on the Fire Behaviour of Thin Film Intumescent Coatings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ming%20Chian%20Yew">Ming Chian Yew</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20Kun%20Yew"> Ming Kun Yew</a>, <a href="https://publications.waset.org/abstracts/search?q=Lip%20Huat%20Saw"> Lip Huat Saw</a>, <a href="https://publications.waset.org/abstracts/search?q=Tan%20Ching%20Ng"> Tan Ching Ng</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajkumar%20Durairaj"> Rajkumar Durairaj</a>, <a href="https://publications.waset.org/abstracts/search?q=Jing%20Han%20Beh"> Jing Han Beh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyzes the fire protection performance, char formation and heat release characteristics of the thin film intumescent coatings that incorporate waste eggshell (ES) as a nano bio-filler.

As a result, ES nano bio-filler composition good to slow down the fire expanding and demonstrate better fire protection due to its positive synergistic effect with flame retardant ingredients on physical and chemical reactions in fire protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cone%20calorimeter" title="cone calorimeter">cone calorimeter</a>, <a href="https://publications.waset.org/abstracts/search?q=eggshell" title=" eggshell"> eggshell</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20protection" title=" fire protection"> fire protection</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20release%20rate" title=" heat release rate"> heat release rate</a>, <a href="https://publications.waset.org/abstracts/search?q=intumescent%20coating" title=" intumescent coating"> intumescent coating</a> </p> <a href="https://publications.waset.org/abstracts/86229/effects-of-flame-retardant-nano-bio-filler-on-the-fire-behaviour-of-thin-film-intumescent-coatings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86229.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">2653</span> Correlation Volumic Shrinkage, Conversion Degree of Dental Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Amirouche">A.

Watts </a> </p> <p class="card-text"><strong>Abstract:</strong></p> During polymerization of dental composites, the volumic shrinkage is related to the conversion degree. The variation of the volumic shrinkage (S max according to the degree of conversion CD.), was examined for the experimental composites: (BisGMA/TEGDMA): (50/50), (75/25), (25/75) mixed with seven radiopac fillers: La2O3, BaO, BaSO4, SrO, ZrO2 , SrZrO3 and BaZrO 3 with different contents in weight, from 0 to 80%. We notice that whatever the filler and the composition in monomers, Smax increases with the increase in CD. This variation is, linear in particular in the case of the fillers containing only one heavy metal, and that whatever the composition in monomers. For a given salt, the increase of BisGMA composition leads to significant increase of S max more pronounced than the increase in CD. The variation of ratio (S max / CD.) with the increase of filler content is negligible. However the fillers containing two types of heavy metals have more effect on the volumic shrinkage than on the degree of conversion. Whatever the composition in monomer, and the content of filler containing only one heavy atom, S max increases with the increase in CD. Nevertheless, S max is affected by the viscosity of the medium compared with CD. For high percentages of mineral fillers (≥ 70% in weight), the diagrams S max according to CD are deviated of the linearity, owing to the fact that S max is affected by the high percentage of fillers compared with CD. The number of heavy atoms influences directly correlation (S max / CD.). In the case of the two mineral fillers: SrZrO3 and BaZrO3 ratio (S max / CD) moves away from the proportionality. The linearity of the diagrams Smax according to CD is less regular, due to the viscosity of high content of BisGMA. The study of Smax and DC of four commercial composites are presented and compared to elaborate experimental composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dental%20composites" title="Dental composites">Dental composites</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20of%20conversion" title=" degree of conversion"> degree of conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=volumic%20shrinkage" title=" volumic shrinkage"> volumic shrinkage</a>, <a href="https://publications.waset.org/abstracts/search?q=photopolymerization" title=" photopolymerization "> photopolymerization </a> </p> <a href="https://publications.waset.org/abstracts/19487/correlation-volumic-shrinkage-conversion-degree-of-dental-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19487.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">373</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">2652</span> Evaluation of PTFE Composites with Mineral Tailing Considering Friction, Wear and Cost</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ant%C3%B4nio%20P.%20de%20Ara%C3%BAjo%20Neto">Antônio P. de Araújo Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruy%20D.%20A.%20da%20Silva%20Neto"> Ruy D.

The majority of relevant test methods are mechanical methods with low repeatability and consistency of results. Thus, this research aims to evaluate the physicochemical interactions of bitumen and aggregates based on the wettability concept. As such, the surface energies of components at the interface are measured by contact angle method. That gives an opportunity to investigate the adhesion properties of multiple mineral fillers at various percentages to explore the best dosage in the mix. Three types of fillers, such as hydrated lime, ground lime and rock powder, are incorporated into the bitumen mix for a series of sessile drop tests for both aggregates and binders. Results show the variation of adhesion properties versus filler (%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adhesion"
