Corrosion of the reinforcements in the concrete has been considered as the severe factor which reduces the concrete structure’s durability. The structures present in marine environments are prone to the corrosion attacks. The damage of concrete is evidenced through expansion, cracking, and gradual concrete cover spalling. The non-uniformity of corrosion throughout the rebar and reduced cross section causes sudden failure of reinforced members without prior indication. With intense earnestness, the corrosion effect on normal steel and high-strength steel which is used in prestressed concrete is discussed here to understand the state of the art. The study included reasons for corrosion of bar and effect on bond strength, structural performance of normal and prestressed concrete. The paper concludes with pores distribution on the concrete, concrete–steel and an aggregate–paste interface contribute more for rebar corrosion and lowers the bond strength, structural performance of RCC structures.
