Abstract: Plain cement concrete is strong in compression and weak in tension which fails on application of tensile load. This research focuses on the eradication of such catastrophic failure in plain cement concrete by the utilization of crimped polypropylene fibres in high strength concrete. Experiments involving the addition of fibres in concrete have increased now days for its application in field practices ranging from steel, glass, polyester, polypropylene etc. In our present study, polypropylene fibres were added in the relative volume fractions of 0.1%, 0.2% and 0.3% with w/c ratio of 0.35. Various studies like compressive strength, split tensile strength and flexural strength at the age of 7 days and 28 days under normal curing and steam curing were performed and the behaviour of fibres was studied. Results concluded that addition of crimped fibres at 0.3% under steam curing had improved the behavioural properties of the concrete.
