Corrosion Damage in Reinforced Concrete - Mears Corrosion
Reinforced concrete is an extremely important material of construction. One reason for the success of this combination is the similarity of thermal expansion properties of carbon steel and concrete. Another is that the extremely high pH of the cement content (typically pH > 13 for new concrete) passivates the steel surfaces against corrosion activity.
