Electrochemical treatments of corroded reinforcement in concrete

Electrochemical treatment methods have been used to arrest corrosion and protect the serviceable life of a structure. This paper analyses the corrosion initiation mechanisms, the chemical reactions taking place at the steel interface and the transportation process. The available options are briefly discussed and their advantages and disadvantages examined. The conclusions drawn, focus on the current practice and how the discussed electrochemical treatments can be used to optimize performance.
