Abstract: Self-compacting concrete (SCC) is a highly flowable, non-segregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation. This study was made on fresh and hardened properties of self compacting concrete (SCC) blended with mineral admixtures like fly ash(25%), metakaolin(5%), silica fume(5%) and chemical admixture Conplast SP 337 as super plasticizer. Sand plays a very important role for imparting better properties to concrete in its fresh and hardened state. It also affects many concrete properties, including workability and finishability. sBased on the guidelines given by EFNARC the mix design for SCC is obtained by replacing natural river sand with robosand, with various FM 2.5, 2.7, 2.9. The fresh and hardened properties of SCC are tested after 7, 28 and 90 days.
