This Digest, which is aimed at building owners, lessors and engineers, describes three techniques for assessing reinforcement corrosion using electrochemical methods: measurements of resistivity, half-cell potential and corrosion current. Their advantages and disadvantages are discussed together with criteria for the interpretation of collected data. Finally, three examples of the practical application of embedded and retrofitted corrosion probes are briefly described. 12 pages.
