Research ArticleOpen accessIn the keywordsUtilization of Bone Adhesive to Produce Particleboards from Stems of Cotton Plant at the Pressing Temperature of 140°CKomi Kadja, Magolmeena Banna, Kokou Esso Atcholi, Komla SandaProblem statement: To value agricultural residues, a study was carried out to investigate mechanical and physical properties of particleboards produced from stems of cotton (Gossypium hirsutum L.) by using bone adhesive. Approach: In order to obtain particleboards with minimum physical and mechanical properties as required in the conventional standards for general purpose particleboards, the optimum pressure temperature and the optimum … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,270 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsFreezing 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 PDF Cite

Research ArticleOpen accessIn the abstractStrength Modeling of High-Strength Concrete with Hybrid Fibre ReinforcementA. Ravichandran, K. Suguna, P. N. RagunathThe low tensile strength and limited ductility, the unavoidable deficiency, of concrete can be overcome by the addition of fibres. High strength concrete (HSC) of 60 MPa containing hybrid fibres, combination of steel and polyolefin fibres, at different volume fraction of 0.5, 1.0, 1.5 and 2.0% were compared in terms of compressive, splitting tensile strength and flexural properties with HSC … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,541 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDuctility Performance of Hybrid Fibre Reinforced ConcreteS. Eswari, P.N. Raghunath, K. SugunaThis study presents a study on the ductility performance of hybrid fibre reinforced concrete. The influence of fibre content on the ductility performance of hybrid fibre reinforced concrete specimens having different fibre volume fractions was investigated. The parameters of investigation included modulus of rupture, ultimate load, service load, ultimate and service load deflection, crack width, energy ductility and deflection ductility. … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,290 accessesView PDF Cite
