ABSTRACT

Corrosion of steel in concrete is a well known problem with severe economic consequences. Steel in concrete is expected to be protected from corrosion due to the barrier that concrete provides and/or the passive and protective film (s) formed on the steel due to the alkaline environment associated with the concrete [1]. This protection can be jeopardized when critical chloride concentrations are achieved [2], however, the mechanism by which this takes place is not clearly understood.
