摘要
PROBLEM TO BE SOLVED: To provide a desalination processing system for concrete capable of grasping a salt content in concrete quantitatively and in a state of being close to a real time, and determining a finish time point of desalination processing.SOLUTION: A desalination processing system for concrete comprises: voltage application means for applying DC voltage in which an anode 30 is installed on a surface of a concrete structure and a reinforcement or a steel frame is a cathode 20; alkaline solution arrangement means for arranging an alkaline solution in the vicinity of the anode; and desalination processing control means to which a detection signal of a salt content detection electrode wire 60 inserted into a sensor insertion hole is input, for determining whether a salt content of the concrete structure is reduced and the salt content is stabilized to a passive state area of a reinforcement or a steel frame, and continuing electrophoresis of chloride ion to an anode side from the vicinity of the reinforcement or steel frame which serves as a cathode by power supply by the voltage application means and the alkaline solution arrangement means.SELECTED DRAWING: Figure 1
