Reinforced concrete is the most common engineering material for civil structures. The durability of the concrete structures depends mainly on the corrosion of steel reinforcement. In general, concrete produces an alkaline environment for steel which passivates it, so preventing corrosion. Provided this passivity is maintained, no problem should arise with steel reinforcement. However, in certain environment, chloride ions can locally destroy very protective passive film of reinforcement even though concrete is still alkaline. This paper presents the corrosion results of reinforcing steel in concrete members in marine environment using the AC impedance technique and DC method.
