EFFECT OF CEMENT COMPOSITION ON CORROSION OF REINFORCING STEEL IN CONCRETE

The tricalcium aluminate present in portland cement is known to be effective for chloride removal and can thus provide protection against steel corrosion. Contradictions are found in the literature with regard to the minimum tricalcium aluminate content of a cement which is desirable to prevent corrosion of reinforcing steel in concretes exposed to chlorides. A review of published experimental data and some theoretical considerations are presented to show that not only the amount of tricalcium aluminate present but also its crystallographic type and the source of chloride are necessary factors in predicting the corrosion behavior of steel in reinforced concrete.
