EXPERIMENTAL INVESTIGATION ON GLASS FIBRE REINFORCEMENT POLYMERS REBARS

In this research we are studying about Glass fiber reinforced polymer (GFRP) Bar and its importance. In recent constructions, Corrosion of steel is one of the main deteriorating mechanisms that significantly degrades traditionally reinforced concrete elements due to environmental impacts, leading to a reduced service-life of infrastructure components. To overcome this we use GFRP bar because It is cheaper than steel. The considerably new FRP rebar technology is based onpultruded composite products, which are made from longitudinally bundled fibers along the bar axis embedded in a resin matrix. The fibers are the main load carrying component and the resin binds the fibers together, and therefore, transfers the load between individual fibers while protecting them from chemical and physical attacks. Now a days , the most widely used fiber type for FRP rods in the United States is glass based for the production of Glass Fiber Reinforced Polymer (GFRP) rebars. E and E-CR(Electrical/Chemical Resistant) glass fibers are the most commonly used ones because they possess high tensile strength, offer high chemical resistance, and feature low production cost. Further we are going to investigate the behaviour of steel and GFRP bars in concrete with regards to bonding and flexure. We are going to compare normal steel bar with GFRP bar by using various standard test.
