Corrosion of Embedded Materials

For steel in concrete, the passive corrosion rate is typically 0.1 m per year. Without the passive film, the steel would corrode at rates at least 1,000 times higher (ACI222 2001). Because of concretes inherent protection, reinforcing steel does not corrode in the majority of concrete elements and structures.
