Types and Causes of Concrete Deterioration
2014. 4. 14. · Concrete and the Passivating Layer Although steel’s natural tendency is to undergo corrosion reactions, the alkaline environment of concrete (pH of 12 to 13) provides steel with corrosion protection. At the high pH, a thin oxide layer forms on the steel and prevents metal atoms from dis-
