The findings of a study on Self Compacting Concrete (SCC), made using natural and manufactured sand (M-sand) are presented. The referral SCC (M25) was made by substituting a part (20%) of Ordinary Portland Cement (OPC) with Class-F Fly Ash (FA). The other SCCs were made by replacing parts of natural sand (NS) with M-sand, by mass. The workability parameters of SCCs in fresh state were determined as per the recommendations EFNARC-2005. The specimen of both SCCs were cast and tested for important strength parameters at different ages as per Indian Standards. It is found that 50% of NS can be replaced by M-sand. The specimen's water absorption was also studied up to 90 days.
