    摘要: The present invention provides a method of inhibiting or preventing corrosion of reinforced steel in concrete by eliminating the differences in surface potentials that result in the total pasivation of corrosion activity and create an environment in the steel that does not allow corrosion. The method, optimally includes measuring the active non-uniform surface potential in the steel and passing a DC voltage through the concrete and steel to stop corrosion providing a substantially uniform potential on the reinforced steel. The current is controlled and adjusted to send pre-determined amounts of electrical energy to individual areas targeted for treatment. A corrosion potential survey may be conducted to determine the energy requirements necessary for the corrosion condition or a reference electrode may be strategically placed on the concrete structure. The amount of energy passed is sufficient to polarize the reinforcing steel sufficiently to stop corrosion and establish substantially uniform surface potentials on all the reinforcing steel. The invention also includes changing conditions on the surface of steel from a condition of non-uniform surface potential to a condition of substantially uniform surface potential.

    摘要: The invention relates to the galvanic protection of a concrete structure (10) comprising metal reinforcements (12). Holes (15) are previously made in the structure, for receiving sacrificial anodes. Before arranging said sacrificial anodes, decontamination electrodes (16) and an electrolyte are inserted into the holes in order to carry out a decontamination phase wherein the negative terminal of a power supply (18) is electrically connected to the reinforcements of the structure and the positive terminal of the power supply is electrically connected to the decontamination electrodes. Once the power supply has been activated for a certain amount of time in order to attract the chloride ions to the decontamination electrodes and the electrolyte, the electrolyte and the decontamination electrodes are removed from the holes (15) and the sacrificial anodes are sealed therein and then electrically connected to the reinforcements.
