Study On Strength Properties Hybrid Fibre Reinforced Concrete

Abstract

An enormous increase in construction activities has resulted in a large scale consumption of basic materials for making concrete. Performance of conventional concrete (CC) is enhanced by the addition of fibre to it. The brittleness of concrete is reduced and its ductility is adequately improved by the addition of fibre to it. In this thesis concrete cubes, cylinders and prisms were cast using M30 grade concrete designated as per relevant Indian standard. The steel, polypropylene (PP) and hybrid polypropylene (PP) and steel (crimped) fibres were used individually in various proportions, i.e., 4% of steel fibre, 4% of polypropylene (PP) fibre and 4% of combined hybrid polypropylene (PP) and steel (crimped) fibres by weight of cement in the preparation of concrete mixes.
