Abstract: In the percent work, attempt has been made to improve the performance of self-compacting composite concrete by using recycled coarse aggregate, fly ash and steel fibers. The study is carried out by replacing of natural course aggregate with recycled coarse aggregate in self-compacted concrete (SCC) at different percentages like 10%, 20%, and 30%. It is observed that maximum of 30% recycled aggregate can be effectively used in production of SCC without any significant reduction in strength and durability. The present study also aims at improving the shear, flexural and torsional strength of the concrete by addition of fly ash (FA) and steel fibers (SF). In this research work, 20% of fly ash (class-C) is added as a replacement of binder to its weight and 1.5% steel fibers by weight of concrete. Based on the experimental results, it can be seen that the load carrying capacity of composite concrete increased by 40 to 50% than the plain beam along with energy absorption and ductility.
