Abstract:A brief review of deterioration in concrete structures exposed to marine environment is presented. The paper also discusses problems associated with heavily deteriorated concrete piles of a harbor platform and their repair. It also concentrates on factors promoting corrosion of reinforcement in concrete piles causing cracking and spalling of concrete. Ways of assessing the degree of deterioration in concrete piles due to corrosion of steel reinforcement using various tests (visual, electrical potential, strength properties, chloride penetration, carbonation of concrete, etc.) and methods of repair are also presented. The successful method of structural repair can only be achieved by careful diagnosis and fully understanding the nature of the problem. The repair is carried out by removal of concrete from the deteriorated concrete structures.
