✦ Synopsis


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.

## Abstract Chromate, which is known to be an effective corrosion inhibitor in various applications, is contained in cement as a trace element. So far its influence on the corrosion of steel in contact with concrete has not been investigated. However, as the introduction of chromate‐reduced cements
