Abstract: This paper outlines an experimental study that measures the effects of polymer fiber on Mechanical properties of concrete. Polypropylene Fiber Reinforced Concrete is an embryonic construction material. Poly propylene is a 100 % synthetic textile fiber. The present study was to evaluate the mechanical properties of concrete by using PP fibers. Specimens were prepared with various combinations of 0.6%, 0.8 %, 1.0 %, 1.2 %, 1.5 %, and 2.0 % of Polypropylene fibers by volume fraction for all proportions. This paper presents the experimental methodology and experimental result related to Compressive strength of cubes for 3 days, 7 days, and 28 days, 56 days, 90 days. Split tensile strength, flexural strength of Concrete at 28 days of curing was evaluated. Fiber-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. FRP reinforcements offer a number of advantages such as corrosion resistance, non-magnetic properties, high tensile strength, lightweight and ease of handling.
