Abstract

This paper presents the result of an experimental study investigating the effect of steel fibres on the Mechanical properties. In this project, I am going to carry out test on steel fibre reinforced concrete to check the influence of fibres on flexural Test, split tensile strength test of concrete. The main aim of this experiment is to study the strength properties of steel fibre concrete of M20 grade with 0%, 0.25%, 0.5% and 0.75% by volume of concrete from the exhaustive and extensive experiment to work it was found that with increase in steel fibre content there was a increase in flexural and split tensile strength of concrete. It is now well established that one of that the important properties of steel fiber reinforced concrete is its superior resistance to cracking and crack propagation. As a result of this ability to arrest crack, fiber composite posses increased extensibility and tensile strength ,both at first crack and at ultimate ,particular under flexural loading and the fibers are able to hold the matrix together even after extensive cracking. The net result of all these is to impart to fiber composite pronounced post-cracking ductility which is unheard of material would increase substantially the energy absorption characteristics of the fiber composite and its ability to withstand repeatedly applied ,shock or impact loading . In this paper, the mechanics properties, technologies of steel fiber reinforced concrete are discussed.
