Durability Characteristics of GFRP rebar in Concrete

Abstract: Corrosion of internal reinforcing steel is one of the major causes of failure of concrete structures. Composite rebar, glass fiber reinforced polymer (GFRP) reinforcement bar is the solution to corrosion of reinforced concrete structures. The main aim of this study is to present the performance and durability characteristics of GFRP rebar in concrete environment. GFRP rebar consists of composites of resin and glass fibers in which the resin protects the bonding of fibers from disintegration. Fibre reinforced polymer rebar has greater advantage in corrosion resistance than conventional steel rebar.
