- Abstract
- The present study concerns the resistance of calcium aluminate cement (CAC) against steel corrosion. Corrosion behaviour of steel, chloride binding/buffering and chloride transport were evaluated to predict the risk of steel corrosion. The CAC mortar had no corrosion of steel, irrespective of the curing temperature and CAC types, while ordinary Portland cement (OPC) indicated a severe corrosion on the steel surface. The chloride binding capacity for CAC was lower than OPC, but the buffering to a pH decrease was highly ranked in CAC paste. Moreover, ingress of chlorides at all depths was reduced in CAC, imposing the mitigated corrosion risk.
