In this study, the strength performance of concrete with polypropylene (PP) fibre is studied. For this purpose, polypropylene (PP) fibre is added in varying volume fraction (Vf) of 0%, 0.5%, 1%, 1.5% and 2% of M25 grade concrete. The concrete was cast with Ordinary Portland Cement, M-Sand and blue metal, with and without fibres. There is a decrease in workability of concrete when the PP fibre Vf is increased from 0.5% to 2.0%. The compressive, flexural and split tensile strength of concrete have shown an improvement of 7.67%, 26.57% at Vf=1% and 33.61% and Vf=1.5% over conventional concrete. The optimum percentage of polypropylene is found to be 1% beyond which there is a reduction in strength.
