Abstract
A process for rehabilitation of internally reinforced concrete which comprises the temporary application of an adherent coating of an electrolytic material, formed of cellulosic pulp to surface areas of the concrete. Distributed electrode means, preferably a ferrous metal wire grid, is embedded in the adherent coating. Voltage sufficient to develop a current of about 1-5 amps/m.sup.2 is applied between the reinforcement and the distributed electrode, to cause migration of chloride ions from the concrete into the electrolytic coating. When the chloride content of the concrete has been reduced to a desired level, the voltage is discontinued and the electrolytic coating and distributed electrode are removed. Particularly for tensioned reinforcement, the process monitors polarization of the tensioned steel to prevent hydrogen embrittlement.
