Abstract – Secondary reinforcement of the primary building material could bestow additional strength and durability to structure and make it almost time-proof. Concrete have very low tensile strength and little resistance against crack development Fibre Reinforced Concrete (FRC) could improve mechanical properties and controls crack development in concrete. An attempt has been made to improve the mechanical properties of concrete using fiber. Fiber used in this study was Recron 3S of CT 2024 type. Length of the fibre is 12mm.The mechanical properties of Recron 3S fibre at 0.1%, 0.25% & 0.5% of cement content used in concrete were studied. Compressive strength of cube (15cm x 15cm x 15cm), split tensile strength of cylinder (15cm diameter x 30cm height) and flexural test of prism (10cm x 10cm x 50cm) of concrete in various percentage of fibre were studied. The result was compared with the M25 control concrete. Compressive strength, split tensile strength and modulus of rupture of 0.25% of FRC was 40.2 MPa, 3.87 MPa and 5.15 MPa respectively. Compared to control concrete compressive strength, split tensile strength and modulus of rupture of 0.25% of FRC increases about 15.87%, 13.2% and 16.3% respectively
