Determining the corrosion state of steel reinforcement in concrete

The corrosion of reinforced concrete structures is a major issue in the UK and worldwide from both a structural view and maintenance management aspect. Early detection of this degradation process will provide the owner with the optimum number of repair options whilst minimising repair costs. This paper reports on the new non-destructive corrosion detection technique for reinforced concrete – AeCORR, specifically targeted towards detecting active corrosion damage occurring within the concrete during the very early stages of the degradation process. An overview of the technique is provided together with a recent case study.
