Effect of sulphate on the corrosion of reinforcing steel in concrete
Highlights Sulphate ions are slightly corrosive to reinforcing steel. The corrosivity of sulphate is lower than that of chloride ions. The combined effect of sulphate and chloride leads to high corrosion rates. The effect of sulphate should be considered in the design of long-term durability structures. Corrosiveness of sulphate is a concern to long-term durability reinforced concrete structures.
Abstract The corrosion rate of concrete reinforcement bars (rebars) in the presence of sulphate, and its effect when combined with chlorides was investigated, in the context of radioactive waste management. It was found that the presence of sulphate alone as well as the combined effect with chloride increase the corrosion rate of rebars. Based on these results, the selection of the site of construction of a radioactive waste repository is crucial to comply with the durability requirements of the facility.
