  • Patent number: 11879885
    Abstract: An electrochemical measurement system for monitoring a concrete structure having a reinforcement bar, including: at least six electrodes to contact the concrete structure's surface, including at least two emitting electrodes to inject electrical signals into the structure and at least four receiving electrodes combined in pairs, each pair receiving electrical signals, originating from an explored zone of the structure located beneath an axis connecting the electrode pairs with its depth depending on the distance between the two electrodes in the pair; an acquisition module to (i) control the electrodes and (ii) acquire and store in a memory the electrical signals; a processing module to calculate, for the electrical signals, induced polarization potential response value(s) and one apparent resistivity value; from these values, process output characteristic(s) of each explored zone; an image reconstruction module to generate an image of the distribution of the output characteristic(s) in the explored zones.
