Steel fiber and fly ash are common additives that can improve concrete performance. Steel fiber improves the tensile and flexural 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 flexural strength 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 mm, 30 mm and 40 mm and 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 results are analyzed and compared with a control specimen. The specimens are tested for flexural strength. This project also aims to determine the optimum content of flyash and steel fiber that can produce the maximum flexural strength property.
