  • PDF Types and Causes of Concrete Deterioration

    Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan-sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling (Figs. 1 and 2).

  • Corrosion of All Kinds| Concrete Construction Magazine

    We know that corrosion of steel in reinforced concrete causes severe distress in structures. Corrosion can occur when concrete loses its high alkalinity (about a pH of 12.5 to 15). Reinforced concrete must be of high quality—primarily low water-cement (w/c) ratio—to maintain its high alkalinity, which it does by minimizing depth of carbonation.
