Reinforced concrete is a composite material. Its structural performance is realized only when concrete and steel act in unison during the service life of the structure. The comprehensive and tensile loads are carried by concrete and steel respectively. Steel protects concrete from cracking under tensile loads and concrete protects steel from corrosion by providing an alkaline environment around it. So long as this happens, the reinforced concrete structures perform satisfactorily. Even though the concrete can be a very strong material,…
