Abstract
Re-usable, energy-efficient apparatus for the restoration of corrosion-damaged reinforced concrete and a method for controlling the same. The apparatus includes a combination electrode device in a sandwich construction that includes a dimensionally stable electrode, a reusable electrolyte reservoir, an ion exchanger element, a reference electrode, a power-switching device for anodic regulation, and a measuring system for determining the capacity of the ion exchanger element to take up ions. Use of this combination electrode device prevents the formation of active chlorine during extraction of chlorine from reinforced concrete.
Claims25
