Abstract

Results of accelerated laboratory studies reported in this paper show that a high tricalcium aluminate content of cement has a significant beneficial effect on reinforcement corrosion resistance performance of concrete structures. On an average, a 9.5% Type I cement performs 1.62 times better than a 2.8% C₃A Type V cement in terms of corrosion initiation time for embedded reinforcement. This appears to be due to the complexing ability of C₃A with free chlorides in cement.
