A study is conduct to determine the engineering properties viz. Compressive Strength, tensile strength and water absorption capacity of the partially replacement of river sand and ordinary Portland cement . In recent days the demand for river sand is increasing due to its lesser availability. Hence the practice of partially replacing river sand with M-Sand and ordinary Portland cement with lime stone powder is taking a tremendous growth. It is also inferred from the literature that partially replacement of normal sand with M-Sand and ordinary Portland cement with lime stone powder produces no appreciable increase in compressive and tensile strength due to the variation in mix ratio. The lime stone powder obtained from limestone quarries. The concrete are made using varying contents of M-Sand, lime stone powder as fine aggregate and ordinary Portland cement. The Samples of concrete (eg.cubes and cylinders) are made in three different grades, namely: M15, M20 and M25. It was found that 0.50 water/cement ratio produced higher compressive strengths, tensile strength and better workability for M25 mix proportion. Specifically compressive, tensile strength and flexural strength ranged from 18.14 ? 36.72 N/mm2, 10.76 -18.5 N/mm2 and 12.21- 40.08 N/mm2 for the mixes considered. These results compare favorably with those of conventional concrete. The concrete was found to be suitable for use as structural members for buildings and related structures.
