In recent days concrete usage has been increased all over the world. Concrete is one of the most developed materials. Different types of waste materials used in concrete as fiber reinforcement to develop its mechanical performance. Steel fiber is such type of waste material used in concrete. The main focus of this paper is to improve the compressive and tensile strength of concrete using steel fibers as fiber reinforcement. In this paper, several number of normal concrete cylinders and several number of fiber reinforced concrete cylinders with addition of 1%, 2% and 3% of steel fiber are investigated. Several tests have been performed under UTM Machine. Compressive strength & split tensile strength of concrete are found better for 2% addition of steel fiber. This paper shows a summary of the improvement of concrete’s mechanical performance including steel fiber as fiber reinforcement.
