Now a days, repairing and rejuvenation of Structures Cost high as much as the Construction of New Structures. The main reason for repairing of RC Structures are cracks which are induced due to flexural failure of RC Structure. So as to improve the flexural strength, we had found that the addition of fibers especially Hybrid fibers are suitable for flexural failure issue. In this paper flexural behavior of hybrid fiber reinforced concrete beams was investigated. Combination of steel and glass fibers was used as hybrid fibers. In order to obtain benefits of both fibers. The Hybrid concrete beams of concrete were casted as per IS 10262:2009. The Hybrid fibers are added to concrete by 2% of its total volume. Fibers are Hybridized with proportions of (25%S-75%G, 50%S-50%G, 75%S-25%G). Hybrid FRC and control concrete beams were casted and tested.
