Abstract (en)
[origin: WO2018091534A1] The invention relates to a method for determining a state of corrosion and passivation on a steel concrete component (1), in which an inert measuring electrode (3) is arranged on the surface, an electrically conductive connection to a reinforcing steel (2) is established, into which an electrical test signal is fed. A negative cathode protection current (/fc) is fed into the measuring electrode (3). On the measuring electrode (3), a corrosion measurement signal (Sl, Sl') for determining the charges, which are transported by iron ions through the outer concrete layer (1.1), and a moisture measurement signal (S2, S2') for determining the moisture of the outer concrete layer (1.1) are simultaneously measured. The corrosion measurement signal (Sl, Sl ') is compared to a predetermined limit value, when the moisture measurement signal (S2, S2 ') indicates at least one minimum measurement moisture. The invention further relates to an arrangement for carrying out the method.
