Abstract
Corrosion of reinforcement is one of the major durability challenges which leads to a reduction in the design life of reinforced concrete. Due to an increasing demand for longer service lives of infrastructure (typically 100–120 years) and the high cost involved in building and maintaining it, the repair of concrete structures has become extremely important. This paper discusses mechanism of corrosion in reinforced concrete and its thermodynamic and kinetic behaviour. It also presents and compares different corrosion prevention and protection techniques available and recommended by BS 1504-9:2008, including the use of corrosion inhibitors, alternative reinforcement, steel and concrete coating and electrochemical techniques. It is concluded that the electrochemical techniques are more effective than conventional methods.
