Non destructive techniques for on site measurements of reinforcement corrosion in concrete structures
It is recognised that reinforcement corrosion is the main distress behind the present concern regarding concrete durability. In spite of the very numerous papers published on the subject, relatively few are devoted to the development of measurement of on-site techniques in general, and even less to the measurement of corrosion. However, it is known the importance of an accurate (non destructive) on-site identification of the zones suffering corrosion, and in these zones to appraise the importance of this corrosion, that is, the achieved loss in cross section and the rate of its progress. Corrosion measurements techniques are needed or may be applied for identifying corroding zones, predicting the rate of corrosion of reinforcement, predicting the residual life of the structure and monitoring the efficiency of repair systems. In the present paper, a review is made on existing on-site techniques, and on the recent development of new ones, including application examples in reinforcement structures. Embedded sensors, as well as the needed treatment of their expected evolution and integration on time in function of the changes in the climatic conditions in the environment surrounding the concrete structure, are commented too.
