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 abstractAnalysis of the Transport Properties of Tyre Fiber Modified ConcreteG. Senthil Kumaran, M. Lakshmipathy, Nurdin MushuleProblem statement: Nowadays, the use of waste tyre in concrete has become technically feasible and the tyre mixed concrete is light weight and called as rubberized concrete. Still the research is going on to explore basic engineering properties such as transport properties viz, acid absorption test, water absorption tests, impact resistance, modulus of elasticity, dynamic modulus and so on. In … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 30 Sep 2011 · 7,433 accessesView PDFCite
Research ArticleOpen accessIn the abstractInterpolating Operators for MultiapproximationEman Samir BhayaProblem statement: There are no simple definitions of operators for best multiapproximation and best one sided multiapproximation which work for any measurable function in Lp for, p>0. This study investigated operators that are good for best multiapproximation and best one sided multiapproximation. Approach: We first introduced some direct results related to the approximation problem of continuous functions by Hermit-Fejer interpolation … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study of Different Underfill Material on Flip Chip Ceramic Ball Grid Array Based on Accelerated Thermal CyclingZ. Kornain, A. Jalar, N. Amin et al.Problem statement: This study mainly to study the effect of several commercial underfill materials to the reliability of HiCTE Flip Chip Ceramic Ball Grid Array (FC-CBGA) package due to Accelerated Thermal Cycling (ATC) effect. Approach: The warpage condition of package, die back stress, interfacial die shear stress, and solder bump fatigue for different commercial underfills were assessed and compared via … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,195 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Composite Hardened Walls Subjected to Blast LoadsGirum S. UrgessaProblem statement: There is currently no standard design guideline to determine the number of composites needed to retrofit masonry walls in order to withstand a given explosion. Past design approaches were mainly based on simplified single-degree-of-freedom analysis. A finite element analysis was conducted for concrete masonry walls hardened with composites and subjected to short duration blast loads. Approach: The analysis … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,266 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Models for Hardened Properties of Self-Compacting ConcreteArabi N.S. Al Qadi, Kamal Nasharuddin Bin Mustapha, Hashem Al-Mattarneh, Qahir N.S. AL-KadiProblem statement: For predicting workability and hardened properties of Self-Compacting Concrete (SCC) no well known explicit formulation. Approach: Statistical models were carried out to model the influence of key mixture parameter (cement, water to powder ratio, fly ash and super plasticizer) on hardened properties affecting the performance of SCC. Such responses included compressive strength at 3, 7 and 28 days … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,140 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractReliability of Axially Loaded Fiber-Reinforced-Polymer Confined Reinforced Concrete Circular ColumnsVenkatarman Nagaradjane, Pulipaka Narasimharao Raghunath, Kannan SugunaMonte-Carlo simulation based procedure was applied for assessing the reliability of Fiber Reinforced Polymer (FRP) confined reinforced concrete columns. Assessment of reliability provides a quantitative measure of effectiveness of repair. Problem Statement: The procedure presented in the paper could be used for assessing the reliability of reinforced concrete columns before and after the application of FRP wrap, thus helping to … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2009 · 7,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Stress Analysis of the Arterial Wall Utilizing Physiological Pressure WaveformsM.M. Khani, M. Tafazzoli-Shadpour, S. Delavarpour et al.Arterial diseases, promoted by alterations in arterial wall properties, are among the main causes of mortality. Mechanical stresses of the arterial wall caused by pulsatile luminal pressure define arterial function in normal and pathological conditions. This study aims to determine dynamic stress distribution in the arterial wall subjected to physiological pressure waveforms. Finite element models of a typical artery are … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,163 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Bio-Modified Montmorillonite Clay to Enhance Asphalt Oxidation ResistanceShahrzad Hosseinnezhad, Elham H. Fini, Taher M. Abu-LebdehThis study evaluates the effectiveness of using a Bio-modified Nanoclay additive (BNC) to reduce the oxidative aging of asphalt pavements. The study results through X-Ray Diffraction analysis showed that the modification of montmorillonite clay with bio-modifier increased the basal d-spacing of clay. The resulting nanoclay with increased interlayer spacing was chosen for application in asphalt binder. Rheological characterization of clay-modified … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 31 Mar 2018 · 9,054 accessesView PDFCite
