Claim 16:
17. A method for monitoring a concrete structure comprising a reinforcement bar, said method comprising the following steps:
receiving a plurality of electrical signals, originating from an explored zone of the concrete structure, acquired using electrochemical measurement system comprising at least six electrodes;
receiving a model comprising a geometric disposition of the reinforcement bar in the concrete structure, initial values of resistivity and chargeability for the reinforcement bar volumes and initial values of resistivity and chargeability for the concrete volumes;
using the model to calculate for each plurality of electrical signals at least one induced polarization potential response value and one apparent resistivity value, and from these values, process at least one output characteristic of the concrete structure associated to each explored zone from which the plurality of signals originates; wherein one output characteristic of the concrete structure is the corrosion rate of the reinforcement bar; and
generating an image of the distribution of the output characteristics of the concrete structure in the explored zones.
