摘　　要：Nowadays,many research works are carried for all grades of concrete to make the concrete most economical and durable there by adding the supplementary cementitious materials and alternative replacement aggregates.In this research work deals with the experimental investigation of mechanical properties of the M30,M50 and M80 grade concrete by replacing the fine and coarse aggregate by foundry sand and crushed concrete waste respectively.Mix design procedures were followed as per IRC44:2017 guidelines and recommendation.Proper dosage of super plasticizer(SP)was maintained in the concrete to make it better performed.In this present investigation,a Poly Propylene fibre(PPF)of 0.3%by weight of the cement is used.Mechanical properties such as Compressive strength and Flexural Strength were determined by preparing the respective mould sizes for specific test and are cured for 7,14 and 28 days and result obtained for respective days were tabulated and discussed.
