Electrochemical methods, e.g. potential mapping, provide information whether the steel reinforcement 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. Particular the corrosion progress is a significant problem. Especially in the case of element corrosion in reinforced concrete structures, the development at the anode can not be separated into corrosion damage causing by element corrosion or self-corrosion. Until now also in laboratory tests it is impossible to collect such information without destroying specimens after electrochemical testing was performed place. To overcome this problem it was tried to study the steel surface within the mortar specimens by X-ray tomography (CT). Within the scope of these investigations it could be shown, that X-ray tomography is suitable to make corrosion pits visible which are embedded in a mortar with a cover thickness of about 35 mm. In this publication the corrosion damage of reinforced steel is documented timedependent by X-ray tomography.
