Abstract

The interfacial zone between cement paste and embedded steel is a porous one, to which the rust can easily diffuse and where it can be deposited. Strengthening the zone makes the passive oxide film more complete, and harder to rupture; the rate of corrosion decreases, the initiation stage of pitting corrosion is delayed, the effect of self-catalysis is weakened, and the acceleration of corrosion is greatly decreased. Therefore, a strengthened interfacial zone can improve the anti-corrosion properties greatly, with less cost than other methods of inhibiting corrosion.
