Corrosion of reinforcement has been established as the predominant factor causing widespread
premature deterioration of concrete construction worldwide, especially of the structures located in the
coastal marine environment [1]. The most important causes of corrosion initiation of reinforcing steel
are the ingress of chloride ions and carbon dioxide to the steel surface. After initiation of the corrosion
process, the corrosion products (iron oxides and hydroxides) are usually deposited in the restricted
space in the concrete around the steel. Their formation within this restricted space sets up expansive
stresses, which crack and spall the concrete cover. This in turn results in progressive deterioration of
the concrete
