Abstract: Concrete consists of cement, sand, coarse aggregate and water. The critical factor that increases value to concrete is that it tends to be intended to withstand harsh conditions. The concrete industry is continually looking for supplementary cementitious material to reduce the substantial waste disposal problem and depletion of natural resources. The study is done to test the relevant properties using limestone as a partial replacement of cement, polypropylene fibre as an additive in concrete. Lime serves as a substitute for cement and enhances the compressive strength, split tensile strength and flexural strength of concrete. Also adding limestone powder increases the durability of concrete. Polypropylene fibres help in reducing the micro racks of concrete and also increasing the flexural and tensile strengths of concrete. Here we compare, the compressive strengths of different cubes caste with partially replaced limestone powder in the order of 5%, 10%, 15% and 20 %, with that of the nominal concrete cube. Out of the cubes cast above the maximum strength yielded and its corresponding percentage of limestone replacement is noted. The optimum value of fibre is found. The microstructure study of these samples is done using SEM, EDS and FTIR.
