摘要

The reliability of reinforced concrete bridge decks is in many cases governed by durability. Many structures require premature rehabilitation or replacement as a result of environmental deterioration. The durability of concrete bridge decks may be affected by corrosion of reinforcement steel. The corrosion of reinforcement steel arising from the ingress of chloride salts applied to melt snow and ice is a severe problem. Since the reinforced concrete is a composite material, mild steel is used to provide the required tensile properties and to control surface cracking. When reinforcement corrodes, the formation of rust leads to a loss of bond between the steel and concrete; and subsequent spalling and delamination. It impairs not only the appearance of the bridge deck, but also its strength and safety, arising from the reduction in the cross-sectional area of the reinforcement, as a result of the deterioration of bond with the surrounding concrete. The computations discussed in this paper are limited to the determination of chlorides concentration and do not include the effects of rust formation.
