Durability Characteristics of GFRP rebar in Concrete

FRP rebar does not behave in the same manner as steel rebar because the mechanical and durability properties are different in some cases. FRP rebar has higher strength but lower modulus of elasticity, therefore direct replacement of steel is not always possible with FRP rebar in some cases and FRP design codes required.
