Abstract

The results of an experimental investigation to study the effects of hooked steel fibers with varying dosage and polymer latex with fixed dosage in concrete are studied. In this experimental study, varying volume fraction of hooked steel fibers from 0% to 7% by weight of cement at the interval of 1% of fiber and SBR latex polymer of fixed volume of 15% by weight of cement were used. All specimens of only fiber content were water cured and specimens of polymer with fiber content were air cured. At the end of 28 days of curing period, destructive tests were carried out on concrete specimens to determine the elastic constants of fiber reinforced concrete and polymer modified steel fiber reinforced concrete. For the analysis of structures, the elastic constants are very important. The elastic constants are static modulus of elasticity (Es), dynamic modulus of elasticity (Ed), Poisson’s ratio (μ) and modulus of rigidity (G), etc.
