concrete, the passive corrosion rate is typically 0.1 µm per year. Without the passive film, the steel would corrode at rates at least 1,000 times higher (ACI 222 2001). Because of concrete's inherent protection, reinforcing steel does not corrode in the majority of concrete elements and structures.
