  • System, electrode and method for evaluating a condition of steel reinforcements in concrete
    Patent number: 11300497
    Abstract: The present disclosure relates to a method, system and electrode for evaluating a condition of steel reinforcements in concrete structures. A reference electrode is positioned on a first area on a concrete structure. An electromagnetic survey is performed to estimate a reference voltage for the reference electrode. A measurement electrode is positioned on a second area on the concrete structure. A difference of potential between the reference electrode and the measurement electrode is determined. A voltage at the measurement electrode is determined based on the reference voltage and on the difference of potential. A corrosion probability at the second area is determined based on the voltage at the measurement electrode. Several electrodes may be placed in an array. Any one of the electrodes may be moved to various areas on the concrete structure.
