Sources of natural sand for use as an aggregate in concrete in construction are becoming scarce as sand pits are exhausted and environmental legislation prevents dredging. So it has become obligatory for us to search for a new feasible solution. In this research proposal an effort has been made to give a viable solution for this problem. Manufactured sand produced from sandstone is used as fine aggregate for concrete. 100% River sand is replaced with M – Sand including microfines. Microfines are the particles of size less than 75µm. M30 grade of concrete is made with varying % of microfines (0%, 5 %, 10 %, 15%, 20% and 25%). Six mixes of M – Sand and one mix of river sand were made for trial and compared. Manufactured sand with appropriate amount of microfines showed increased compressive strength.
