摘要：Concrete offers many advantages regarding mechanical characteristics and economic aspects of theconstruction, the brittle behaviour of the material remains a larger handicap for the seismic and other applicationswhere flexible behaviour is essentially required. Polypropylene fiber-reinforced concrete (PFRC) has provided atechnical basis for improving these deficiencies.Polypropylene is one of the cheapest and abundantly availablepolymers. Chemical inertness makes the polypropylene fibers resistant to most chemicals. Its melting point is highranges between 159 􀀀 - 179 􀀀. So that it can withstand a working temperature of 100 􀀀 for short periods withoutdetriment to fiber properties. In the present research work the mix design of grade M25 was calculated to prepare theconcrete specimens for the different proportion of polypropylene fiber such as 0 kg/m3, 3 kg/m3, 4 kg/m3 and 5 kg/m3(i.e. 0%, 0.12%, 0.16% and 0.2%). For each grade of concrete, cube specimen was cast, cured and tested at 7 & 28 daysto assess the compressive strength of the concrete. Cylinder and prism were cast cured and tested for each grade ofconcrete for 28 days maturity to assess the split tensile strength and flexural strength of the concrete. Behaviour ofstructural member (RCC beam) has also been studied in the present research work with different proportion ofpolypropylene fiber. Finally the results of specimens of various percentages of fibers in concrete have been comparedand the result of the project is explained.
