Jul 17, 2020  July 17, 2020. Corrosion is a natural process that begins when the steel rebar within reinforced concrete starts to rust. According to ACI, “corrosion occurs when the protective layer in concrete steel reinforcement is destroyed. Steel in concrete is usually protected against corrosion by the high pH of the surrounding portland-cement paste.”.
