ABSTRACT

Corrosion of steel reinforcement in concrete exposed to chloride containing environments is a serious problem in civil engineering practice. Electrochemical methods, e.g. potential mapping, (SIA 2006, DGZfP 1990) provide information whether the reinforced steel is still passive or depassivation has been initiated. By applying such techniques no information on the type of corrosion, its extent and distribution of corrosion products is available. Until now it is impossible to collect such information without destroying specimens after electrochemical testing has taken place.
