Abstract


The electrochemical process of steel corrosion in concrete are studied by simulating its liquid phase with synthetical solutions in a large range of hydroxyls, carbonates and chlorides ions.The steel specimen is either under or without an electrical polarization. The present analysis has made it possible to define a new relevant parameter, which is the [CΓ]/[AIK] ratio (where AIK is the total alkalinity). It characterizes the conditions of the polarized steel pitting corrosion. Furthermore, the investigation showed out that a polarization at potentials lower than — 700 mVSCE, stops the corrosion processes.
