Abstract – Steel fiber and fly ash are common additives that can improve concrete performance. Steel fiber improves the tensile properties of concrete whereas fly ash acts as partial substitute for cement in concrete. This paper incorporates both the properties of steel fiber and fly ash. This project aims to investigate the mechanical properties of steel fiber reinforced concrete with the addition of fly ash. The study is carried out in M25 mix. Steel fibers varied from 0%,0.5%,1%,1.5% of different aspect ratios 20, 30 mm and 40 mm replacement of fly ash varies from 10%,20% and 30%. The specimens are generally tested for7 and 28 days and the behaviour of fly ash based steel fiber reinforced concrete were studied. The specimens are generally tested for compressive strength, tensile strength and flexural strength. This project also aims to determine the optimum content of fly ash and steel fiber that can produce the maximum strength properties. This paper also considers the effect of high range water reducing agent on the workability of fly ash based steel fiber reinforced concrete.
