Abstract

The corrosion of rebar is one of the main problem in the construction industry. A lot of amount is spent on the repair work every year but none of them is that effective. Therefore, the recent studies are being conducting on the FRP rebar due to the brittle nature and the bonding performance. We have also used PVA fiber in concrete to increase the strength of the concrete. we are using Hybrid beams in which we have replaced the corner rebar with BFRP bars because of their superior corrosion effect and the strength to weight ratio. We used four point loading test on these hybrid reinforced beams to find the flexural behaviour by which we can predict the performance. 0.25% PVA fiber reinforced concrete showed the optimum results.
