Concrete is a composite material made from cement, water, fine aggregate and coarse aggregate. But present researchers are in interest of finding new cementing materials by waste materials or waste products produced from industries which are disturbance to human life. Our project deals on M25 grade of concrete by partial replacement of cement with fly ash and steel fibers are added to the concrete volume. First fly ash having high silica content is made partial replacement of cement in 10%, 15%, 20%, 25% and optimum percentage of replacement is found out without loss of strength. Now steel fibers are added to the optimum fly ash replacement in volumetric ratio of concrete. Steel fibers are added in 0.5% , 1.0% and 1.5% and optimum percentage of steel fibers is determined. All the cubes and cylinders are tested at 7 days, 28 days & 56 days.
