Research ArticleOpen accessIn the abstractInfluence of Acid Frosting on the Microstructure Characteristics and Mechanical Strength of Eroded Soda-Lime-Silica Glasses by SandstormAkinwumi Gbenga Owoyemi, Grace Olufunke Matthew, Seun Samuel OwoeyeMost glass products such as cars windshields, solar panels protecting glass and windowpanes are exposed to unavoidable sandblasting effects especially in areas prone to sandstorms. This sand impingement results into micro cracks and surface flaws which altered the structure and strength of the exposed glasses thereby lowering their service life. In this regard, attempt was made in this research to … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 25 Apr 2019 · 6,918 accessesView PDFCite
Research ArticleOpen accessIn the abstractBehavior of Lightweight Coarse Aggregate RC Beams with Circular OpeningAdel A. Al-AzzawiThis pressent research investigates the mechanical properties of Waste Rubber Fibers Lightweight Coarse Aggregate Concrete (WRFLWAC) mixture. Also, the shear behaviors of 12 RC beams contain opening are investigated. The main study parameters are: The opening location, the waste rubber fiber ratio and the shear reinforcement. Deflection values and cracks are registered at each load step; also the cracking or … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 1 Apr 2017 · 7,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanical Properties of Waste Biaxially Oriented Polypropylene Metallized Films (BOPP), LLDPE: LDPE Films with Sisal FibresKiran Rohit, Savita DixitThe current work describe the enhancement and improvisation of polymer composite repose of sisal fiber reinforcement, Biaxially Oriented Polypropylene (BOPP) and thermoplastic LLDPE: LDPE particulate fillers. The composite were prepared with fiber content 5, 10, 15 and 20% (by weight). The composite are characterized with respect to their mechanical properties (Tensile, flexural and impact strength) were studied. Tensile strength showed … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 2 Nov 2016 · 8,374 accessesView PDFCite
Research ArticleOpen accessIn the abstractBIODEGRADABILITY AND MECHANICAL BEHAVIOUR OF SUGAR PALM STARCH BASED BIOPOLYMERJ. Sahari, S. M. Sapuan, E. S. Zainudin, M. A. MalequeA new Sugar Palm Starch (SPS) based biopolymer was successfully developed using glycerol as plasticizer. The effect of glycerol concentration (viz., 15, 20, 30 and 40 by weight percent) to the mechanical properties of plasticized SPS biopolymer was investigated. From this investigation, it was found that the 30% glycerol concentrated biopolymer showed the highest flexural strength and impact with the … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 10 Nov 2014 · 7,704 accessesView PDFCite
EditorialOpen accessIn the abstractRECENT TRENDS AND CHALLENGES OF ENERGY EFFICIENT AND SUSTAINABLE BUILDINGSChiara BedonAccording to several studies (e.g., the Intergovernmental Panel on Climate Change (IPCC, 2014), the US Energy Information Administration (US EIA, 2014), warming of the climate system is unequivocal and mainly derives from greenhouse gas emissions due to human activities. Global Carbon Dioxide (CO2) emissions from fossil fuels, for example, are estimated to be 29% higher in 2035 than they were … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 11 Sep 2014 · 8,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Water on The Strength of Building StonesBellopede Rossana, Marini PaolaProblem statement: Water is one of the main causes of stone decay and the presence of water alone inside a stone could cause a decrease in its mechanical strength. In order to study the effect of water on the mechanical strength of stones, three Italian stones, which have historically been used for balconies, have been studied: Pietra di Luserna, Pietra … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 17 Mar 2012 · 7,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractProperties of Fly Ash Based Coconut Fiber CompositeK. Saravana Raja Mohan, P. Jayabalan, A. RajaramanThe present paper reports the results of a study undertaken in enhancing properties of fly ash concrete composites-FMCC with locally available natural fiber. In this context a composite with fly ash, concrete and treated coconut fibers-available in plenty in rural areas of India-can be a good proposition and with this background, experimental investigation to study the effects of replacement of … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 20 Feb 2012 · 9,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractShear Strength of Reinforced Concrete Beam Strengthened by Transverse External Post-tensionSayan Sirimontree, Boonsap Witchayangkoon, Nathavudh Khaosri, Jaruek TeerawongProblem statement: Shear failure of concrete beam is brittle manner without warning so inadequate design for shear of beam and/or material deterioration lead to the possibility of sudden failure of beam. The change of functional use and future increased load of structure lead to the need for strengthening of concrete structure. Approach: This research focuses on behaviors under static loading … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2011 · 8,863 accessesView PDFCite
Research ArticleOpen accessIn the abstractFreezing and Thawing Durability of Very High Strength ConcreteSameer Hamoush, Miguel Picornell-Darder, Taher Abu-Lebdeh, Ahmed MohamedProblem statement: The newly developed Very High Strength Concrete (VHSC), having compressive strengths of 29 ksi and flexural strengths of 6 ksi, represents a breakthrough in concrete technology. Study to further enhance the properties of this new concrete is continuing. Approach: The objective of this study is to investigate the effect of exposing Very High Strength Concrete (VHSC) specimens to … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 28 Jan 2011 · 8,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluences of Short Discrete Fibers in High Strength Concrete with Very Coarse SandMahyuddin Ramli, Kwan Wai HoeProblem statement: High Strength Concrete (HSC) normally content high cementitous amount and low water binder ratio. However, these would cause substantial volume changes to the concrete and therefore affected the strength development. In addition, the brittleness of HSC was increased when silica fume used as partial cement replacement to achieve high strength. Approach: This study discussed the effects of incorporated … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,812 accessesView PDFCite
