The use of steel in concrete has increased massively in the last century, and it is now one of the most commonly used building materials on earth (second to water in usage by mankind). The biggest durability problem with structures of this material is corrosion of the steel reinforcement. The cause of this corrosion that is most difficult to remedy is the presence of chloride in the concrete, which allows the steel to corrode at a rapid rate. Because of the huge economic significance of this problem over the last 50 years, there has been almost continuous research in many countries to categorise the problem.

Cathodic protection of reinforced concrete structures is a technique for rescuing corrosion damaged structures and, in certain instances, preventing them from corroding in the first place, and its use is growing.

This book is for specialist contractors, large consultants and owners of corrosion damaged structures, and looks at international experience with this technique. It examines why corrosion is occurring, the differences in the application of CP with the stark dichotomy in its success and failure, and finally ways in which its performance can be improved on future installations. Information is valuable, as the success or failure of the CP system has a marked effect on the service life of the structure.
