Abstract

This experimental work describes the mechanical properties of concrete on addition of steel and propylene. Steel and polypropylene fiber together are known as Hybrid Fiber Reinforced concrete(HFRC).HFRC is prepared by adding any two fibers to the conventional concrete to make it a composite mixture and that derives benefits from each of the added fiber and exhibits significant response. Here the polypropylene fibers helps in resisting initial cracks and shrinkage, steel fibers helps in increase the strength of concrete. In present work M35 grade of concrete can be prepared according to the IS 10262:2009 reference code. these steel and polypropylene fibers are added by 50% each with different hybridization from 0% to 1.5%. For calculating strength parameters specimens are casted and cured for 28 days and tested in the lab for Compressive Test, Split Tensile Test and Flexural Test. From the present investigation the strength parameter increases with the percentage of increase in fiber. Therefore here the hybrid ratio of 1.5% gives the more result when compared to other hybrid ratio.
