DURABILITY OF CORROSION RESISTING STEELS IN CONCRETE

A ten-year exposure study has examined the performance of reinforcing steels with higher than normal corrosion resistance embedded in concrete. The steels included in the programme were a weathering steel, galvanized steel, types 405 and 430 ferritic and types 302, 315 and 316 austenitic stainless steels. The performance was compared with that of grit-blast cleaned and pre-rusted high-yield steel. The concretes examined (1:6 and 1:8 cement : aggregate mixes) contained a range of added chloride to enhance corrosion activity. The results have illustrated the excellent resistance of the austenitic stainless steels in comparison with all the other steels when embedded in concrete containing the highest concentrations of chloride. They have also indicated the corrosive nature of the chloride ion and underline the need to control chloride concentrations to the limits now set in BS 8110. (a)
