EFFECT OF TRICALCIUM ALUMINATE CONTENT OF CEMENT ON CORROSION OF REINFORCING STEEL IN CONCRETE

Results of accelerated laboratory studies reported in this paper show that a high tricalcium aluminate content of cement has a significant benficial 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. (Author/TRRL)
