ABSTRACT:
A corrosion measuring cell for establishing the start of corrosion and/or for measuring the degree of corrosion of structural or reinforcing steel, which is embedded in a concrete structural part, has a corrosion-resistant cathode electrode, and several ordinary steel anode electrodes spaced from one another at different distances from the external surface of the concrete structural part.
The anode electrodes are each connected to a cathode electrode through a current-measuring device which measures current due to corrosion at the anodes in order to establish the temporal course of carbonatization or chloridization taking place in the concrete. The connections may be switched between the measuring device and a polarizing device which polarizes the anode electrode in such a manner that the corrosion current, and thus the corrosion of the anode electrode, stops when desired to avoid damage to the concrete.
