Cathodic Protection of Reinforced Concrete – State of the Art and Case Studies

Chloride induced corrosion of the reinforcing steel is one of the major causes of premature failure of concrete structures exposed to marine environment. Cathodic prevention systems are now widely recommended for new reinforced concrete structures that are to be exposed to chloride environments. The cathodic prevention systems are built in during construction to prevent corrosion of the reinforcement. This paper describes the design, installation and commissioning of impressed current CP system installed recently in new wharf structures in Portugal.
