Research ArticleOpen accessEvery word in the titleSelecting Natural Fibers for Bio-Based Materials with Conflicting CriteriaFaris M. AL-Oqla, Mohd Sapuan Salit, Mohamad Ridzwan Ishak, Nuraini Abdul AzizProper material selection enhances both desired physical and meta-physical properties of the end user products. Due to the growing awareness of the environmental issues as well as the industrial sustainability, the Natural Fiber Composites (NFCs) have recently emphasized to be implemented in various industrial applications. The final product features of such composites depend on the integrated characteristics of both matrix … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 16 Mar 2015 · 8,760 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluences 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
Research ArticleOpen accessEvery word in the titleRate Effect on Pullout Behavior of Steel Fibers Embedded in Very-High Strength ConcreteTaher Abu-Lebdeh, Sameer Hamoush, Brian ZornigProblem statement: Rate dependence of the newly developed Very-High-Strength-Concrete (VHSC) composites has received little or no attention so far. Approach: In this research, the bond-slip mechanisms of four types of steel fibers embedded in VHSC matrices were investigated through single-fiber pullout tests with the loading rates and matrix strengths are the primary variables. This study presented the experimental results of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,438 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePullout Characterizations of Various Steel Fibers Embedded in Very High-Strength ConcreteSameer Hamoush, Taher Abu-Lebdeh, Toney Cummins, Brian ZornigProblem statement: There is a real need for a fundamental understanding of bond and bond mechanisms in the newly developed Very-High-Strength-Concrete (VHSC) materials. The interfacial steel fiber/VHSC matrix bond tests are needed to characterize VHSC and to aid in the development of analytical models that describe bond behavior of this new material. Approach: This research investigated bond-slip characteristics of four … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,067 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Polypropylene Fibers on the California Bearing Ratio of Air Cured Stabilized Tropical Peat SoilBehzad Kalantari, Bujang B.K. Huat, Arun PrasadProblem statement: Peat soil is well known to deform and fail under a light surcharge load and is characterized with low shear strength, high compressibility and high water content. With the rising demand from the construction industry, utilization of these soils is required and suitable technique needs to be found out for stabilizing them. Approach: Model study had been carried … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,697 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Removal of Methyl Red from Aqueous Solutions Using Banana Pseudostem FibersMas Rosemal H. Mas Haris, Kathiresan SathasivamProblem statement: The aim of this study was to investigate the removal of methyl red, a mutagenic monoazo dye, from various aqueous solutions using banana pseudostem fibers of the size 212-350 micron. Approach: The parameters studied were the effect of pH, amount of adsorbent, contact time, concentration of adsorbate and agitation speed. Results: Equilibrium data were fitted to the Langmuir … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 8,298 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleInvestigation of the Characteristics of Thulium Doped Alumina Nanoparticles for Applications in Silica-Based FibersNur Atiqa Bt Rahmat, Hairul Azhar Abd Rashid, H.Y. Wong, Mukter ZamanIt is reported that during the fabrication of doping RE ions into the silica preform, the distribution of particles is inhomogeneous and becomes uneven throughout the fiber which lead to unwanted spectroscopic characteristics. It is assumed that by using thulium doped with alumina, the problem with the inhomogeneity of the particles inside the fiber can be solved. With the incorporation … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,411 accessesView PDFCite
