Research Status of Durability of FRP Rebars

Taking the place of reinforcing bar,the fiber reinforced polymer(FRP) rebar is used to reinforce the concrete member is a feasible way to solve the main problem of reinforcing bar corrosion for concrete structures.However,durability of FRP rebar is related to material composition,properties as well as bar-concrete interaction,and its durability corrosion mechanism is complex.The research status of durability of FRP rebars under temperature,moisture,acidic and alkali environment and ultraviolet exposure are summarized,which would provide a reference for the future study.
