Abstract

The galvanic currents between carbon steel and Cr-bearing rebars have been studied in concrete subjected to carbonation and chloride attack. The results revealed that in case of SD345 contacted with Cr-bearing rebar in concrete under chloride attack environment and carbonation environment, the corrosion acceleration by galvanic corrosion is not generated. Therefore, Cr-bearing rebar can be used together with the carbon steel in the new establishment structure.
