Abstract
The present understanding of selected corrosion phenomena in reinforced concrete is reviewed. Special emphasis is given to chloride induced corrosion.
There is a general acceptance of the basic corrosion mechanism for steel in concrete. However different anodic reactions governing the subsequent formation and composition of corrosion products have been proposed.
Suggested reactions, except half-cell reactions, are verified or rejected based on their Gibbs free energy, while the electrode potential is calculated for half-cell reactions. Corrosion products postulated to form are related to observations.
A thermodynamically possible reaction mechanism for the formation of green rust in the presence of chlorides is proposed. Initial verification of the suggested mechanism is given based on experimental data from the literature and own observations.
