(Reapproved 2006) REINFORCEMENT FOR CONCRETE— …

the tension in these members due to beam action (Fig. 2.2.1(c)). Steel is remarkably well- suited for concrete reinforcement because it has high tensile strength, and therefore relatively small amounts are required. Also, concrete bonds to steel, and both expand and contract to about the same degree with temperature changes.

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).
