Flexural Behavior of Cementitious Composites Reinforced by Synthetic Fibers
The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...
متن کاملTetrametallic lanthanide(III) phosphonate cages: synthetic, structural and magnetic studies.
The synthesis, structures and magnetic properties of a family of lanthanide complexes containing phosphonate ligands are reported. Reaction of hydrated lanthanide nitrate and (t)butylphosphonic acid under reflux conditions in iso-butanol, in the presence of pivalic acid as a co-ligand produced five new lanthanide complexes; pyridine (py) was present as a base. The compounds formed are tetrameta...
متن کاملPulmonary effects of exposure to synthetic fibers: A case study in a textile industry in Iran
Background & Aims of the Study: Industries continue to develop and use of various types of manmade fibers nowadays. Acrylic fiber is one of the most important synthetic fibers that use in industries. Based on this fact that, little information exists about workplaces exposure to acrylic fibers, purpose of this study is to determine so this study has been done for evaluation of the pulmonary eff...
متن کاملNovel nano cellulosic fibers for remediation of heavy metals from synthetic water
The increased surface area-to-volume ratio of nanoparticles, quantum size effects and the ability to tune surface properties through molecular modification make nanostructures ideal for environmental remediation. The present piece of work reports the preparation and characterization of nano cellulosic fibers (NCFs) with further polymeric reinforcement using vinyl sulphonic acid for the remediat...
