Concrete is often considered to be the ultimate construction material. Normal concrete is a vibrated concrete and it is dense aggregate mix that requires mechanical vibrations or poking to remove air pockets that become trapped during the pouring and mixing process. Hence to overcome these defects the selfcompacting concrete is used. Although SCC was originally used in specialized situations, over time it became a superior alternative to conventional vibrated concretes. The self-compacting concrete flows easily at suitable speed into formwork without blocking through the reinforcement without being heavily vibrated. The major steps in the production of Self Compacting Concrete are proper design of mixes, the selection of admixtures that has the ability to maintain fluidity of mix and evaluating the properties of the concrete obtained. This project deals with the flexural strength of self- compacting concrete where the cement is partially replaced with fly-ash as10%, 20%, and 40% by weight of cement. . The optimized dosage of super plasticizer of 0.5% of powder content is used in each mix. The flexural strength characteristics are studied.
