Different types of Deterioration in Concrete Structures
The production steps that transform iron ore into steel add energy to the metal. The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. Essentially, the iron in the steel is oxidised to produce rust, which occupies a greater volume than the steel.
