This can lead to a change in the dimensions of the acrylic resin material. If repeated immersions were done, its strength would be affected. Disinfectant solutions have been widely used to reduce microorganisms both inside and outside the patient's mouth. One of the disinfecting materials that can be used is a clover solution. The purpose of this research is to find the ratio of water absorption of the acrylic resin material of self-cured type, soaked in clover solution for 10 minutes. The results showed that the average value obtained before soaked in clover solution was 0.0692 mg/cm3 and after soaked, in clover solution, the value was 0.090 mg/cm3. The conclusion of this research shows that the values of water sorption of acrylic resin before and after soaked in clover solution is still in ISO standard 1567/2001. Differences in water sorption value of self-cured acrylic resin before and after the immersion are caused by the process of liquid diffusion into the acrylic resin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorption%20of%20fluid" title="absorption of fluid">absorption of fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=self-cured%20acrylic%20resin" title=" self-cured acrylic resin"> self-cured acrylic resin</a>, <a href="https://publications.waset.org/abstracts/search?q=soaked" title=" soaked"> soaked</a>, <a href="https://publications.waset.org/abstracts/search?q=clover%20solution" title=" clover solution"> clover solution</a> </p> <a href="https://publications.waset.org/abstracts/87144/water-sorption-of-self-cured-resin-acrylic-soaked-in-clover-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87144.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">163</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">452</span> The Performance and the Induced Rebar Corrosion of Acrylic Resins for Injection Systems in Concrete Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20S.%20Paglia">C.

Among the different resins, a methacrylate-based type of acrylic resin significantly inhibited the rebar corrosion. This was mainly caused by the relatively high pH of the resin and the resin aqueous solution. This resin also exhibited a relatively high sealing performance, in particular after exposing the resin to durability tests. The corrosion inhibition behaviour and the sealing properties after the exposition to durability tests were maintained up to one year. The other resins either promoted the corrosion of the rebar and/or exhibited relatively low sealing properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acrylic%20resin" title="acrylic resin">acrylic resin</a>, <a href="https://publications.waset.org/abstracts/search?q=sealing%20performance" title=" sealing performance"> sealing performance</a>, <a href="https://publications.waset.org/abstracts/search?q=rebar%20corrosion" title=" rebar corrosion"> rebar corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=materials" title=" materials"> materials</a> </p> <a href="https://publications.waset.org/abstracts/113691/the-performance-and-the-induced-rebar-corrosion-of-acrylic-resins-for-injection-systems-in-concrete-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113691.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">451</span> Chemical and Physical Modification of Carbon Fiber Reinforced Polymers Based on Thermoplastic Acrylic Resin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamil%20Dydek">Kamil Dydek</a>, <a href="https://publications.waset.org/abstracts/search?q=Szymon%20Demski"> Szymon Demski</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamil%20Majchrowicz"> Kamil Majchrowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulina%20Kozera"> Paulina Kozera</a>, <a href="https://publications.waset.org/abstracts/search?q=Bogna%20Sztorch"> Bogna Sztorch</a>, <a href="https://publications.waset.org/abstracts/search?q=Dariusz%20Brz%C4%85kalski"> Dariusz Brząkalski</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuzanna%20Krawczyk"> Zuzanna Krawczyk</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Przekop"> Robert Przekop</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Boczkowska"> Anna Boczkowska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thanks to their excellent properties, i.e. high stiffness and strength in relation to their weight, corrosion resistance, and low thermal expansion, Carbon Fiber Reinforced Polymers (CFRPs) are a group of materials readily used in many industrial sectors, e.g. aviation, automotive, wind energy. Conventional CFRPs also have their disadvantages, namely, relatively low electrical conductivity and brittle cracking. To counteract this, a thermoplastic acrylic resin was proposed, which was further modified by the addition of organosilicon compounds and multi-walled carbon nanotubes (MWCNTs). The addition of the organosilicon compounds was aimed at improving the dispersion of the MWCNTs and obtaining good adhesion between the resin and the carbon fibre, where the MWCNTs were used as a conductive filler. In addition, during the fabrication of laminates using the infusion method, thermoplastic nonwovens doped with MWCNTs were placed between the carbon reinforcement layers to achieve a synergistic effect with an increase in electrical and mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFRP" title="CFRP">CFRP</a>, <a href="https://publications.waset.org/abstracts/search?q=acrylic%20resin" title=" acrylic resin"> acrylic resin</a>, <a href="https://publications.waset.org/abstracts/search?q=organosilicon%20compounds" title=" organosilicon compounds"> organosilicon compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20properties" title=" electrical properties"> electrical properties</a> </p> <a href="https://publications.waset.org/abstracts/153127/chemical-and-physical-modification-of-carbon-fiber-reinforced-polymers-based-on-thermoplastic-acrylic-resin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153127.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">128</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">450</span> The Impact of Initiators on Fast Drying Traffic Marking Paint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Taheri">Maryam Taheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jahanfar"> Mehdi Jahanfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenji%20Ogino"> Kenji Ogino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fast drying traffic marking paint comprising a solvent-borne resin, a filler, a pigment and a solvent that is especially suitable for colder ambient (temperatures near freezing) applications, where waterborne traffic paint cannot be used.

Its printing process consists of using a light emitter to solidify photosensitive liquid resins layer-by-layer to produce solid objects. However, the majority of the resins used in SLA are derived from petroleum and characterized by toxicity, stability, and recalcitrance to degradation in natural environments. Aiming to develop an eco-friendly resin, in this work, different combinations of a standard commercial SLA resin (Peopoly UV professional) with a vegetable-based resin were investigated. To reach this goal, different mass concentrations (varying from 10 to 50 wt%) of acrylated epoxidized soybean oil (AESO), a vegetable resin produced from soyabean oil, were mixed with a commercial acrylate-based resin. 1.0 wt% of Diphenyl(2,4,6-trimethylbenzoyl) phosphine oxide (TPO) was used as photo-initiator, and the samples were printed using a Peopoly moai 130. The machine was set to operate at standard configurations when printing commercial resins. After the print was finished, the excess resin was drained off, and the samples were washed in isopropanol and water to remove any non-reacted resin. Finally, the samples were post-cured for 30 min in a UV chamber. FT-IR analysis was used to confirm the UV polymerization of the formulated resin with different AESO/Peopoly ratios. The signals from 1643.7 to 1616, which corresponds to the C=C stretching of the AESO acrylic acids and Peopoly acrylic groups, significantly decreases after the reaction. The signal decrease indicates the consumption of the double bonds during the radical polymerization. Furthermore, the slight change of the C-O-C signal from 1186.1 to 1159.9 decrease of the signals at 809.5 and 983.1, which corresponds to unsaturated double bonds, are both proofs of the successful polymerization. Mechanical analyses showed a decrease of 50.44% on tensile strength when adding 10 wt% of AESO, but it was still in the same range as other commercial resins. The elongation of break increased by 24% with 10 wt% of AESO and swelling analysis showed that samples with a higher concentration of AESO mixed absorbed less water than their counterparts. Furthermore, high-resolution prototypes were printed using both resins, and visual analysis did not show any significant difference between both products. In conclusion, the AESO resin was successful incorporated into a commercial resin without affecting its printability. The bio-based resin showed lower tensile strength than the Peopoly resin due to network loosening, but it was still in the range of other commercial resins. The hybrid resin also showed better flexibility and water resistance than Peopoly resin without affecting its resolution. Finally, the development of new types of SLA resins is essential to provide new sustainable alternatives to the commercial petroleum-based ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D-printing" title="3D-printing">3D-printing</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-based" title=" bio-based"> bio-based</a>, <a href="https://publications.waset.org/abstracts/search?q=resin" title=" resin"> resin</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean" title=" soybean"> soybean</a>, <a href="https://publications.waset.org/abstracts/search?q=stereolithography" title=" stereolithography"> stereolithography</a> </p> <a href="https://publications.waset.org/abstracts/130419/acrylate-based-photopolymer-resin-combined-with-acrylated-epoxidized-soybean-oil-for-3d-printing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130419.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">128</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">448</span> Finite Element Analysis of Dental Implant for Prosthesis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mayur%20Chaudhari">Mayur Chaudhari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashutosh%20Gaikwad"> Ashutosh Gaikwad</a>, <a href="https://publications.waset.org/abstracts/search?q=Shubham%20Kavathale"> Shubham Kavathale</a>, <a href="https://publications.waset.org/abstracts/search?q=Aditya%20Mule"> Aditya Mule</a>, <a href="https://publications.waset.org/abstracts/search?q=Dilip%20Panchal"> Dilip Panchal</a>, <a href="https://publications.waset.org/abstracts/search?q=Puja%20Verma"> Puja Verma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this investigation was to locate restorative bio-materials for the manufacture of implants and crowns. A three-dimensional (3D) finite element analysis (FEA) was carried out to evaluate the stress distribution in the implant and abutment with several types of bio-materials and various prosthetic crowns. While the dental implant, abutment, and screw were subjected to a vertical impact force, the effects of mechanical characteristics such as Young's modulus and Poisson's ratio were evaluated and contrasted. Crowns are made from zirconia, cobalt, ceramic, acrylic resin, and porcelain materials. Implants are made from materials such as titanium, zirconia, PEEK, and CFR-PEEK. SolidWorks was used to create the 3D geometry, and Ansys Software was used to analyze it. The results show that using CFR-PEEK implants and an acrylic resin crown resulted in less bone stress than using alternative materials. In order to reduce the amount of stress on the bone and possibly prevent implant failure, the study's findings support the use of a CFR PEEK implant, abutment, and crown in bruxism patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomaterials" title="biomaterials">biomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=implant" title=" implant"> implant</a>, <a href="https://publications.waset.org/abstracts/search?q=crown" title=" crown"> crown</a>, <a href="https://publications.waset.org/abstracts/search?q=abutment" title=" abutment"> abutment</a> </p> <a href="https://publications.waset.org/abstracts/179033/finite-element-analysis-of-dental-implant-for-prosthesis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179033.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">60</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">447</span> Colonization of Candida Albicans on 3D Printed CAD/CAM Complete Denture Versus Conventional Complete Denture: Randomized Controlled Clinical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20Helal">Eman Helal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20M.%20Esmat"> Ahmed M.

Purpose evaluation of the antibacterial characteristics of the 3D printed CAD/CAM denture and to compare it with the conventional heat polymerized acrylic denture base material. Methodology a total of thirty completely edentulous patients grouped randomly into two groups (Group I: Control group) received conventional heat polymerized acrylic resin complete dentures, (Group II: Test group) received 3D printed (CAD/CAM) dentures (stereolithographic PMMA), Samples of Candida albicans culture swabs were taken after 1 month and 3 months of dentures` insertion. A culture swab was obtained by scrubbing the fitting surface of the upper denture. At each time interval, three swab samples were collected from each patient and were inoculated in three individual culture media. Results: there was a significant difference in the colonization of Candida albicans to the fitting surface of the dentures between both groups (Group I: Conventional denture cases) exhibited more adhesion of Candida Albicans to the fitting surface than did (Group II: CAD/CAM cases) (P<0.05). Conclusion: 3D printed CAD/CAM complete denture showed minimal Candida adherence upon upper denture fitting compared to conventional heat-polymerized acrylic resin, which contributes to decreasing the incidence of denture stomatitis which is considered one of the most common problems among complete denture wearers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CAD%2FCAM%20denture" title="CAD/CAM denture">CAD/CAM denture</a>, <a href="https://publications.waset.org/abstracts/search?q=completely%20edentulous" title=" completely edentulous"> completely edentulous</a>, <a href="https://publications.waset.org/abstracts/search?q=elderly%20patients" title=" elderly patients"> elderly patients</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title="3D printing">3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20efficiency" title=" antimicrobial efficiency"> antimicrobial efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20denture" title=" conventional denture"> conventional denture</a>, <a href="https://publications.waset.org/abstracts/search?q=PMMA" title=" PMMA"> PMMA</a>, <a href="https://publications.waset.org/abstracts/search?q=Candida%20Albicans" title=" Candida Albicans"> Candida Albicans</a>, <a href="https://publications.waset.org/abstracts/search?q=denture%20stomatitis" title=" denture stomatitis"> denture stomatitis</a> </p> <a href="https://publications.waset.org/abstracts/145127/colonization-of-candida-albicans-on-3d-printed-cadcam-complete-denture-versus-conventional-complete-denture-randomized-controlled-clinical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145127.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">139</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">446</span> Dynamic Foot Pressure Measurement System Using Optical Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tanapon%20Keatsamarn">Tanapon Keatsamarn</a>, <a href="https://publications.waset.org/abstracts/search?q=Chuchart%20Pintavirooj"> Chuchart Pintavirooj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Foot pressure measurement provides necessary information for diagnosis diseases, foot insole design, disorder prevention and other application.

However, the repeatable quality of the product can be achieved by critically fixing the process parameters such as Vacuum Pressure (VP) and permeability of the preform. The present investigation is aimed at studying the effect of permeability for production of Glass Fiber Reinforced Plastic (GFRP) components with consistent quality. The VARTM mould is made with an acrylic transparent top cover to observe and record the resin flow pattern. Six layers of randomly placed glass fiber under five different vacuum pressures VP1 = 0.013, VP2 = 0.026, VP3 = 0.039, VP4 = 0.053 and VP5 = 0.066 MPa were studied. The laminates produced by this process under the above mentioned conditions were characterized with ASTM D procedures so as to study the effect of these process parameters on the quality of the laminate. Moreover, as mentioned there is a considerable effect of permeability on the impact strength and the void content in the laminates under different vacuum pressures. SEM analysis of the impact tested fractured GFRP composites showed the bonding of fiber and matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=permeability" title="permeability">permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20assisted%20resin%20transfer%20molding%20%28VARTM%29" title=" vacuum assisted resin transfer molding (VARTM)"> vacuum assisted resin transfer molding (VARTM)</a>, <a href="https://publications.waset.org/abstracts/search?q=ASTM%20D%20standards" title=" ASTM D standards"> ASTM D standards</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a> </p> <a href="https://publications.waset.org/abstracts/97819/effect-of-permeability-on-glass-fiber-reinforced-plastic-laminate-produced-by-vacuum-assisted-resin-transfer-molding-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97819.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">160</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">444</span> The Flexural Strength of Fiber-Reinforced Polymer Cement Mortars Using UM Resin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Ho%20Kwon">Min Ho Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Woo%20Young%20Jung"> Woo Young Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Su%20Seo"> Hyun Su Seo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Polymer Cement Mortar (PCM) has been widely used as the material of repair and restoration work for concrete structure; however a PCM usually induces an environmental pollutant. Therefore, there is a need to develop PCM which is less impact to environments. Usually, UM resin is known to be harmless to the environment. Accordingly, in this paper, the properties of the PCM using UM resin were studied. The general cement mortar and UM resin was mixed in the specified ratio. A certain percentage of PVA fibers, steel fibers and mixed fibers (PVA fiber and steel fiber) were added to enhance the flexural strength. The flexural tests were performed in order to investigate the flexural strength of each PCM. Experimental results showed that the strength of proposed PCM using UM resin is improved when they are compared with general cement mortar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer%20cement%20mortar" title="polymer cement mortar">polymer cement mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=UM%20resin" title=" UM resin"> UM resin</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=PVA%20fiber" title=" PVA fiber"> PVA fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20fiber" title=" steel fiber"> steel fiber</a> </p> <a href="https://publications.waset.org/abstracts/3903/the-flexural-strength-of-fiber-reinforced-polymer-cement-mortars-using-um-resin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3903.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">343</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">443</span> The Effect of Acrylic Gel Grouting on Groundwater in Porous Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Wagner">S.

In order to allow anhydrous excavation, soil groutings are carried out, which form a water-impermeable layer. As it is injected into groundwater areas, the effects of the materials used on the environment must be known. Developing an eco-friendly, economical and low viscous acrylic gel which has a sealing effect on groundwater is therefore a significant task. At this point the study begins. Basic investigations with the rheometer and a reverse column experiment have been performed with different mixing ratios of an acrylic gel. A dynamic rheology study was conducted to determine the time at which the gel still can be processed and the maximum gel strength is reached. To examine the effect of acrylic gel grouting on determine the parameters pH value, turbidity, electric conductivity, and total organic carbon on groundwater, an acrylic gel was injected in saturated sand filled the column. The structure was rinsed with a constant flow and the eluate was subsequently examined. The results show small changes in pH values and turbidity but there is a dependency between electric conductivity and total organic carbon. The curves of the two parameters react at the same time, which means that the electrical conductivity in the eluate can be measured constantly until the maximum is reached and only then must total organic carbon (TOC) samples be taken. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acrylic%20gel%20grouting" title="acrylic gel grouting">acrylic gel grouting</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20rheology%20study" title=" dynamic rheology study"> dynamic rheology study</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20conductivity" title=" electric conductivity"> electric conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20organic%20carbon" title=" total organic carbon"> total organic carbon</a> </p> <a href="https://publications.waset.org/abstracts/109849/the-effect-of-acrylic-gel-grouting-on-groundwater-in-porous-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109849.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">146</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">442</span> Synthesis of Epoxidized Castor Oil Using a Sulphonated Polystyrene Type Cation Exchange Resin and Its Blend Preparation with Epoxy Resin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20S.%20Sudha">G.

While the application of the epoxy resin has become a hot topic. In this context, we conducted an experimental campaign (48 specimens are tested beakout) whose objective is based on three points: 1- Highlight the importance and influence of important parameters (compressive strength of concrete anchorage length and diameter of the steel bar) on routes (steel-concrete and steel–concrete epoxy resin) 2- Understanding the influence of the parameters mentioned above on the relationship that may exist between the peel strength and slippage. 3- Faces of cracks and failure modes. This study shows that passage of a compressive strength of 40 MPa to 62 MPa increases the adhesion between the steel bar and concrete and for specimens with or without epoxy resin. The loading force was increased form 40 to 81 kM kN, a rate if increase in loading over 100% In addition, for specimens with and without epoxy resin. increased breakout force through a specimen without a specimen with resin ranging from 20% to 32%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epoxy%20resin" title="epoxy resin">epoxy resin</a>, <a href="https://publications.waset.org/abstracts/search?q=peel%20strength" title=" peel strength"> peel strength</a>, <a href="https://publications.waset.org/abstracts/search?q=anchors" title=" anchors"> anchors</a>, <a href="https://publications.waset.org/abstracts/search?q=slip%20diameter%20steel%20rod" title=" slip diameter steel rod"> slip diameter steel rod</a>, <a href="https://publications.waset.org/abstracts/search?q=anchor%20plain%20concrete%20and%20concrete%20with%20moderate%20resistance" title=" anchor plain concrete and concrete with moderate resistance"> anchor plain concrete and concrete with moderate resistance</a> </p> <a href="https://publications.waset.org/abstracts/30250/the-efficiency-of-the-resin-for-steel-concrete-adhesion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30250.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">433</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">436</span> Extraction of Polystyrene from Styrofoam Waste: Synthesis of Novel Chelating Resin for the Enrichment and Speciation of Cr(III)/Cr(vi) Ions in Industrial Effluents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20N.%20Siyal">Ali N.

The PS was functionalized with N, N- Bis(2-aminobenzylidene)benzene-1,2-diamine (ABA) ligand through an azo spacer. The resin was characterized by FT-IR spectroscopy and elemental analysis. The PS-N=N-ABA resin was used for the enrichment and speciation of Cr(III)/Cr(VI) ions and total Cr determination in aqueous samples by Flame Atomic Absorption Spectrometry (FAAS). The separation of Cr(III)/Cr(VI) ions was achieved at pH 2. The recovery of Cr(VI) ions was achieved ≥ 95.0% at optimum parameters: pH 2; resin amount 300 mg; flow rates 2.0 mL min-1 of solution and 2.0 mL min-1 of eluent (2.0 mol L-1 HNO3). Total Cr was determined by oxidation of Cr(III) to Cr(VI) ions using H2O2. The limit of detection (LOD) and quantification (LOQ) of Cr(VI) were found to be 0.40 and 1.20 μg L-1, respectively with preconcentration factor of 250. Total saturation and breakthrough capacitates of the resin for Cr(IV) ions were found to be 0.181 and 0.531 mmol g-1, respectively. The proposed method was successfully applied for the preconcentration/speciation of Cr(III)/Cr(VI) ions and determination of total Cr in industrial effluents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=styrofoam%20waste" title="styrofoam waste">styrofoam waste</a>, <a href="https://publications.waset.org/abstracts/search?q=polymeric%20resin" title=" polymeric resin"> polymeric resin</a>, <a href="https://publications.waset.org/abstracts/search?q=preconcentration" title=" preconcentration"> preconcentration</a>, <a href="https://publications.waset.org/abstracts/search?q=speciation" title=" speciation"> speciation</a>, <a href="https://publications.waset.org/abstracts/search?q=Cr%28III%29%2FCr%28VI%29%20ions" title=" Cr(III)/Cr(VI) ions"> Cr(III)/Cr(VI) ions</a>, <a href="https://publications.waset.org/abstracts/search?q=FAAS" title=" FAAS"> FAAS</a> </p> <a href="https://publications.waset.org/abstracts/5148/extraction-of-polystyrene-from-styrofoam-waste-synthesis-of-novel-chelating-resin-for-the-enrichment-and-speciation-of-criiicrvi-ions-in-industrial-effluents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5148.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">435</span> Field Trial of Resin-Based Composite Materials for the Treatment of Surface Collapses Associated with Former Shallow Coal Mining</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philip%20T.%20Broughton">Philip T.

A field trial was undertaken by the Coal Authority to investigate the geotechnical performance and potential use of composite materials comprising resin and fill or stone to safely treat surface collapses, such as crown-holes, associated with shallow mining. Test pits were loosely filled with various granular fill materials. The fill material was injected with commercially available silicate and polyurethane resin foam products. In situ and laboratory testing was undertaken to assess the geotechnical properties of the resultant composite materials. The test pits were subsequently excavated to assess resin permeation. Drilling and resin injection was easiest through clean limestone fill materials. Recycled building waste fill material proved difficult to inject with resin; this material is thus considered unsuitable for use in resin composites. Incomplete resin permeation in several of the test pits created irregular ‘blocks’ of composite. Injected resin foams significantly improve the stiffness and resistance (strength) of the un-compacted fill material. The stiffness of the treated fill material appears to be a function of the stone particle size, its associated compaction characteristics (under loose tipping) and the proportion of resin foam matrix. The type of fill material is more critical than the type of resin to the geotechnical properties of the composite materials. Resin composites can effectively support typical design imposed loads. Compared to other traditional treatment options, such as cement grouting, the use of resin composites is potentially less disruptive, particularly for sites with limited access, and thus likely to achieve significant reinstatement cost savings. The use of resin composites is considered a suitable option for the future treatment of shallow mining collapses. <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=ground%20improvement" title=" ground improvement"> ground improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=mining%20legacy" title=" mining legacy"> mining legacy</a>, <a href="https://publications.waset.org/abstracts/search?q=resin" title=" resin"> resin</a> </p> <a href="https://publications.waset.org/abstracts/42787/field-trial-of-resin-based-composite-materials-for-the-treatment-of-surface-collapses-associated-with-former-shallow-coal-mining" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42787.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">355</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">434</span> Synthesis and Application of Tamarind Hydroxypropane Sulphonic Acid Resin for Removal of Heavy Metal Ions from Industrial Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aresh%20Vikram%20Singh">Aresh Vikram Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarika%20Nagar"> Sarika Nagar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The tamarind based resin containing hydroxypropane sulphonic acid groups has been synthesized and their adsorption behavior for heavy metal ions has been investigated using batch and column experiments.

However, the complexity of the flow of the resin in the infusion stage usually leads to nonuniform property distribution of the produced composite part. In order to control the flow of the resin, the situation of flow should be mastered. For the safety of the usage of the produced composite in practice, the understanding of the property distribution is essential. In this paper, we did some trials on monitoring the resin infusion stage and evaluation for the fiber volume fraction distribution of the VARTM produced composite using the digital image correlation methods.

These organic materials are often in contact with a bituminous substrate, which in turn is placed on the ground. In this work, the damage of a basket resin field surface was characterized by means of visual inspection, optical microscopy, resin thickness measurements, adhesion strength, water vapor transmission capacity, capillary water adsorption, granulometry of the bituminous conglomerate, the surface properties, and the water ground infiltration speed. The infiltration speed indicates water pemeability. This was due to its composition: clean sand mixed with gravel. Relatively good adhesion was present between the synthetic resin and the bituminous layer. The adhesion resistance of the bituminous layer was relatively low. According to the required bitumoniousasphalt-concrete mixes AC 11 S, the placed material was more porous. Insufficient constipation was present. The spaces values were above the standard limits, while the apparent densities were lower compared to the conventional AC 11 mixtures. The microstructure outlines the high permeability and porosity of the bituminous layer. The synthetic resin wasvapourproof and did not exhibit capillary adsorption. It exhibited a lower thickness as required, and no multiple placing steps were observed. Multiple cavities were detected along with the interface between the bituminous layer and the resin coating with no intermediate layers. The layer for the pore filling in the bituminous surface was not properly applied. The swelling bubbles on the synthetic pavement were caused by the humidity in the bituminous layer. Water or humidity were present prior to the application of the resin, and the effect was worsened by the upward movement of the water from the ground. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resin" title="resin">resin</a>, <a href="https://publications.waset.org/abstracts/search?q=floor" title=" floor"> floor</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a> </p> <a href="https://publications.waset.org/abstracts/142209/the-damage-and-durability-of-a-sport-synthetic-resin-floor-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142209.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">162</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">430</span> Investigation of Water Absorption and Compressive Strength of Resin Coated Mortar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasir%20Ali">Yasir Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Zain%20Ul%20Abdin"> Zain Ul Abdin</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Wisal%20Khattak"> Muhammad Wisal Khattak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays various advanced techniques are used to enhance the performance of materials in the field of construction engineering. Structures exposed to an aggressive, humid and hostile environment are experiencing severe negative impacts which lead to premature failure. Polyester resin is one of the advanced material used for improving performance of structural materials especially for repair/ refurbish purpose of structures and protection from contaminated environmental effect/ hazards. This study investigated the aptness of the polyester resin as coating agent on the mortar and assessed its performance in an ambient environment of Pakistan. Cubical specimens of mortar were fabricated. These specimens were tested for water absorption and compressive strength after one day and sixty days. These tests were performed under different exposure conditions (ambient environment and submerged in water). The specimens were coated with one, two and three layers and results were compared to control (no/ zero resin layer) specimens. Test results indicated that there is a significant decrease in water absorption of mortar coated with resin when compared to controlled specimens. The compressive strength test results revealed that resin coated specimen had higher strength when compared to controlled specimens. The results suggested that resin is a promising material and can be used effectively in structures which are exposed to high temperatures. The study would be helpful in improving performance of the structural material in a hazardous environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ambient%20environment" title="ambient environment">ambient environment</a>, <a href="https://publications.waset.org/abstracts/search?q=coating" title=" coating"> coating</a>, <a href="https://publications.waset.org/abstracts/search?q=mortar" title=" mortar"> mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=polyester%20resin" title=" polyester resin"> polyester resin</a> </p> <a href="https://publications.waset.org/abstracts/38313/investigation-of-water-absorption-and-compressive-strength-of-resin-coated-mortar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38313.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">356</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">429</span> A Study of Resin-Dye Fixation on Dyeing Properties of Cotton Fabrics Using Melamine Based Resins and a Reactive Dye</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurudeen%20Ayeni">Nurudeen Ayeni</a>, <a href="https://publications.waset.org/abstracts/search?q=Kasali%20Bello"> Kasali Bello</a>, <a href="https://publications.waset.org/abstracts/search?q=Ovi%20Abayeh"> Ovi Abayeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Study of the effect of dye–resin complexation on the degree of dye absorption were carried out using Procion Blue MX-R to dye cotton fabric in the presence hexamethylol melamine (MR 6) and its phosphate derivative (MPR 4) for resination.

In this research, we investigated the effect of nanoparticle addition such as nanoclay and halloysite into urea-formadehyde resin on the total emitted formaldehyde from MDF plates produced using the resin modified as such. First, the curing behavior of the resin was studied by monitoring the pH, curing time, solid content, density and viscosity of the modified resin in comparison to the reference resin with no added nanoparticle. The dosing of the nanoparticle in the dry resin was kept at 1wt%, 3wt% or 5wt%. Consecutively, the resin was used in the production of 50X50 cm MDF samples using laboratory scale press line with full automation system. Modulus of elasticity, bending strength, internal bonding strength, water absorption were also measured in addition to the main interested parameter formaldehyde emission levels which is determined via spectrometric technique following an extraction procedure. Threshold values for nanoparticle dosing levels were determined to be 5wt% for both nanoparticles. However, the reinforcing behavior was observed to be occurring at different levels in comparison to the reference plates with each nanoparticle such that the level of reinforcement with nanoclay was shown to be more favorable than the addition of halloysite due to higher surface area available with the former. In relation, formaldehyde emission levels were observed to be following a similar trend where addition of 5wt% nanoclay into the urea-formaldehyde adhesive helped decrease the formaldehyde emission up to 40% whereas addition of halloysite at its threshold level demonstrated as the same level, i.e., 5wt%, produced an improvement of 18% only. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=halloysite" title="halloysite">halloysite</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoclay" title=" nanoclay"> nanoclay</a>, <a href="https://publications.waset.org/abstracts/search?q=fiberboard" title=" fiberboard"> fiberboard</a>, <a href="https://publications.waset.org/abstracts/search?q=urea-formaldehyde%20adhesive" title=" urea-formaldehyde adhesive"> urea-formaldehyde adhesive</a> </p> <a href="https://publications.waset.org/abstracts/102152/effect-of-nanoparticle-addition-in-the-urea-formaldehyde-resin-on-the-formaldehyde-emission-from-mdf" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102152.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">159</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">427</span> Influence of Degassing on the Curing Behaviour and Void Occurrence Properties of Epoxy / Anhydride Resin System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latha%20Krishnan">Latha Krishnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Cobley"> Andrew Cobley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Epoxy resin is most widely used as matrices for composites of aerospace, automotive and electronic applications due to its outstanding mechanical properties.

For example, degassing (vacuum applied on the mixed resin) has shown higher glass transition temperature (Tg) with lower void content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anhydride%20epoxy" title="anhydride epoxy">anhydride epoxy</a>, <a href="https://publications.waset.org/abstracts/search?q=curing%20behaviour" title=" curing behaviour"> curing behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=degassing" title=" degassing"> degassing</a>, <a href="https://publications.waset.org/abstracts/search?q=void%20occurrence" title=" void occurrence"> void occurrence</a> </p> <a href="https://publications.waset.org/abstracts/40069/influence-of-degassing-on-the-curing-behaviour-and-void-occurrence-properties-of-epoxy-anhydride-resin-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40069.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">216</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">426</span> Effect of the Ratio, Weight, Treatment of Loofah Fiber on the Mechanical Properties of the Composite: Loofah Fiber Resin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Siahmed">F.

This material has attracted attention of the scientific community for its mechanical properties, its moderate cost and its specification as regards the protection of environment. In this study the loofah part of the family of the natural fiber has been used for these significant mechanical properties. The fiber has porous structure, which facilitates the impregnation of the resin through these pores. The matrix used in this study is the type of unsaturated polyester. This resin was chosen for its resistance to long term.The work involves: -The chemical treatment of the fibers of loofah by NaOH solution (5%) -The realization of the composite resin / fiber loofah; The preparation of samples for testing -The tensile tests and bending -The observation of facies rupture by scanning electron microscopy The results obtained allow us to observe that the values of Young's modulus and tensile strength in tension is high and open up real prospects. The improvement in mechanical properties has been obtained for the two-layer composite fiber with 7.5% (by weight). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=loofah%20fiber" title="loofah fiber">loofah fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=loofah%20fiber%20resin" title=" loofah fiber resin "> loofah fiber resin </a> </p> <a href="https://publications.waset.org/abstracts/19900/effect-of-the-ratio-weight-treatment-of-loofah-fiber-on-the-mechanical-properties-of-the-composite-loofah-fiber-resin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19900.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">447</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">425</span> Effect of a Reactive Dye-Resin Complex on Dyeing Properties of Cotton Fabrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurudeen%20Afolami%20Ayeni">Nurudeen Afolami Ayeni</a>, <a href="https://publications.waset.org/abstracts/search?q=Kasali%20Adewale%20Bello"> Kasali Adewale Bello</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Study of the effect of dye-resin complexation on the degree of dye absorption were carried out using Procion Blue MX-R to dye cotton fabric in the presence hexamethylol melamine (MR6) and its phosphate derivative (MPR4) for resination.

Compressive tests, tensile tests and flexural tests were conducted to study the effect of graphene nanoplatelets on neat epoxy resin. By comparing graphene-based and neat epoxy grout, there is no significant increase of strength due to weak interface in the graphene nanoplatelets/epoxy composites. From this experiment, the tension and flexural strength of graphene-based epoxy grouts is slightly lower than ones of neat epoxy grout. Nevertheless, the addition of graphene has produced more consistent results according to a smaller standard deviation of strength. Furthermore, the graphene has also improved the ductility of the grout, hence reducing its brittle behaviour. This shows that the performance of graphene-based grout is reliably predictable and able to minimize sudden rupture. This is important since repair design of damaged pipeline is of deterministic nature. <p class="card-text"><strong>Keywords:</strong> <a
