Abstract
The corrosion of steel refrigerant tubes, embedded in concrete, was investigated at an ice rink in London. A portable linear polarisation surface mounted probe was used to produce both half-cell potential and corrosion rate contour maps. The corrosion rate maps were found to be far more effective and reliable in identifying areas of localised corrosion as confirmed by subsequent break outs and repair.
The paper describes the methodology adopted for obtaining estimates of corrosion rate of steel in concrete using a surface mounted probe, together with the repair strategy adopted.
