Abstract:
The corrosion of steel in reinforced concrete due to the ingress of chlorides is a major cause for the decreased durability of structures built in marine and deicing salt environments. A multitude of research has been conducted to evaluate the corrosion of steel in concrete and to develop protection systems to arrest this process. This paper critically discusses some of the more popular techniques and presents new data illustrating the importance of selecting the right corrosion tests.
