INFLUENCE OF CONCRETE MATERIALS, MIX, AND CONSTRUCTION PRACTICES ON THE CORROSION OF REINFORCING STEEL

The corrosion of reinforcing steel in concrete has been seen most frequently in reinforced concrete highway bridge decks, but also has been observed in bridge support structures, industrial plants, parking garages, and other structures. Characteristics of Portland cement, aggregates, and admixtures conducive to quality concrete are described, including the consequences of poor quality, undesirable chemical contents, physical properties, and good and bad practice with respect to admixtures. Factors influencing quality of concrete include: proper materials specifications, water content, cement content, and design. Importance of plan cover is emphasized, 7.62 cm (3 inches) but not less than 13 to 16 mm (1/2 to 5/8 inch) more than cured cover thickness is suggested. Formulation to give small cracks, allowances for shrinkage, vibration for structures with heavy reinforcing, and proper curing are essential.
