From the review, it is evident that corrosion of reinforce- ment in concrete is a major issue and needs to be considered when designing concrete structures exposed to aggressive environments. Understanding the corrosion process and its thermodynamic and kinetic nature is important for designing a suitable protection strategy. There are various protection techniques available such as corrosion inhibitors, alternative reinforcement, steel and concrete coating and electrochem- ical techniques. However, electrochemical techniques are generally more effective than conventional methods. The suitability of any mitigation technique varies from structure to structure depending upon value engineered, practicality and economic considerations. There is no single best solu- tion for every structure and each one needs to be evaluated on case to case basis. In practice, sometimes, cost pressure based upon client’s requirements leads to the adoption of a particular solution.
