Assessment of corrosion activity in reinforcing steel bars embedded within concrete using the inductive scanning technique

Corrosion processes with time may cause cracking, delamination and finally catastrophic failure of concrete structures. From a safety aspect as well as economic reasons, it is necessary to monitor concrete structures to detect corrosion at its early stages utilizing non-destructive testing techniques. In this paper, a new monitoring technique using inductive scanning technology is presented. Results obtained using this technique are compared with the potential mapping data. The advantages and limitations of both techniques are discussed.
