In today's world concrete technology related to green environment and sustainable development are the two major issues worldwide. Presently non-accessibility of river throughout the year, large scale illegal depletion, rapid growth of construction activities, river water contamination by the harmful chemical wastes from the industry sectors, transportation all the reasons are making the good quality river sand scarcer and costlier. To tackle this problem stone crusher sand (SCS) a waste

CS) a waste material obtained from the crusher plants can be an economical and alternative material .Similarly huge amount of fly ash (FA) is a finely divided by-product powder thrown out as a waste material produced from many thermal power plants .This can be replaced with Ordinary Portland Cement (OPC) with certain amount due to having some cementitious properties efficiently. Lime powder (LP) is used additionally as it is a good binder. This research paper presents the experimental study undertaken to investigate the possible feasibilities of using partial substitution of sand by SCS and OPC by FA with LP in an effective manner .To obtain this, M3O mix design was carried out with replacement of SCS from 0 to 50 percent at 10 percent and FA from 0 to 25 percent at 5 percent interval ranges respectively. After studying the effect of LP on blended cement based concrete its substitution value was fixed as 6 percent. A comparative study was taken at the age of 7 & 28 days strength tests viz. Compressive, split tensile and flexural tests for each replacement with the reference concrete.
