Abstract: This paper focuses on experimental study in the behaviour of polypropylene fibre reinforced concrete. The polypropylene (PP) fibres were mixed into the concrete in the form of reinforcement into the concrete with uniform orientation of the fibres. By adding polypropylene(PP) fibre in concrete the crack formation reduces. Polypropylene (PP) fibre is also heat resistant that is advantageous over polyethylene fibre.The tests on the concrete were conducted after adding polypropylene (PP) fibres into the concrete in different contents, i.e.; 1.5%, 1.75%, 1.85% of the cement mass. Polypropylene is one of the cheapest and abundantly available polymers. Chemical inertness makes the polypropylene fibers resistant to most chemicals. In this paper the relationship between cube compressive strength and cylinder split tensile strength for conventional and polypropylene fibre reinforced concrete were established and compared with standards. The study prompted the substantial improvement in compressive and tensile strength for concrete mixes reinforced with polypropylene fibres. Use of polypropylene (PP) fibre and E waste in M25 concrete increases the flexible strength, prevents the crack an also increases the impact strength of concrete.Positioned on test results obtained 1.5% of polypropylene (PP) fibre addition found to be optimal percentage of polypropylene (PP) fibers. The optimal percentage of polypropylene (PP) fibre 1.5% is used in the experiment. M25 grade of concrete achievement is assessed with respect to slump test, compressive strength, split tensile strength and flexural strength.
