Durability of Concrete Bridges in Virginiaby Celik Ozyildirim, Virginia Transportation Research, Council, Charlottesville, United States,
Abstract: This paper discusses four major types of deterioration found in concrete bridges: corrosion of the reinforcement, alkali-aggregate reactivity, freeze-thaw deterioration, and attack by sulfates. These types of deterioration are caused by improper matching of ingredients and environmental conditions and poor construction practices. For each type, the mechanism of deterioration and the measures taken to prevent the deterioration are discussed.
