Abstract: The Polypropylene fibre reinforced concrete (PPFRC) contains very short discrete Polypropylene fibres which act as an internal reinforcement so as to enhance the properties of the concrete. Addition of discrete fibres into a cement mix reduces the cracking in elastic range, increases tensile strength, deformation capacity and toughness of the composite. These properties of PPFRC primarily depend upon length and volume of propylene fibres (PPF) used in the concrete mixture. In India the polypropylene fibre reinforced concrete has limited applications in several structures. The applications are mainly to inhibit the cracking. However due to the lack of awareness, proper design guidelines specifications, its uses are very limited. Therefore there is a need to upgrade information on the properties of Polypropylene Fibre Reinforced Concrete (PPFRC). For the study, polypropylene fibres of lengths 6 mm with 0.1 %, 0.2%, 0.5 %, 1%, 1.25%, 1.5% and 2% volume fractions are used. The result reported includes an experimental investigation for measurement of workability of PPFRC using standard test method and a selected mechanical property of PPFRC to study the effect of volume fraction of (PPF) for predicting PPFRC in compression
