Due to incremental growth in the use of concrete, these days many ingredients of concrete are in scarcity. Hence supplementary cemetitious materials are being widely used. The current study aims at using supplementary cemetitious materials as well as partially replacing coarse aggregate in M25 grade concrete. Cement is partially replaced by 5%,10%,15% and 20% of fly-ash, coarse aggregate is partially replaced by 2%,4%,6% and 8% of coconut shells. In this project M25 grade concrete is used as
