Correcting and Preventing Concrete Corrosion

Nov 06,  · Corrosion Mechanisms of Reinforcing Steel. In new concrete, alkaline (high pH) conditions form a passive film on the surface of the steel rebar rods, thus preventing or minimizing corrosion initially.But eventually, a pH reduction caused by carbonation or by ingress of chlorides (salt) causes the passive film to degrade, allowing the reinforcement to corrode in the presence of oxygen and moisture.
