This study investigate the behavior of reinforced concrete beams under static flexural load developed with mono fiber and hybrid fibers reinforced concrete. Hybridation is to improve the flexural performance of simply supported reinforced concrete beams. In this investigation, five different mixes are investigated under flexure. Two mono fiber reinforced concrete beam with Steel fiber and Polyethylene Terephthalate (PET) fiber fiber of 2.0% volume fraction mixes. Hybrid fiber reinforced concrete mix with recycled PET bottle fiber of 0.5% hybrid with 1.5% of steel fiber, PET fiber of 1.0% and steel fiber of 1.0% and PET fiber of 1.5% and steel fiber of 0.5% are the other three mixes under investigation. The flexural properties of concrete beam without fiber reinforcement is used as the base mix for comparison. From the results, it has been studied that hybrid fiber reinforced concrete beams performed better than the all the other mixes.
