ELECTROCHEMICAL TREATMENT METHOD AND APPARATUS OF CONCRETE SURFACE FOR ARREST ALKALI IONS LEACHING FROM CONCRETE AND CONCRETE STRUCTURE THEREOF

摘要

The present invention relates to a method for inhibiting the leaching of hydroxide ion (OH ^- ), which is a main agent of alkali ions, by forming a calcium hydroxide film on the surface of concrete through an electrochemical treatment technique and thereby inhibiting the leaching of alkali ions And an object of the present invention is to provide a concrete structure and an electrochemical concrete surface treatment apparatus and method for the same. According to an aspect of the present invention, there is provided an electrochemical concrete surface treatment method for suppressing alkali ion leaching, comprising: a step of installing a conductive metal plate on a surface of a concrete having a plurality of reinforcing bars disposed therein; An energizing step of energizing the reinforcing bars as an anode material and using the conductive metal plate as a cathode material so as to form a calcium hydroxide film at the interface between the concrete surface and the conductive metal plate; And a control step of controlling a current, a voltage, and an energization time to be energized in the energizing step, thereby providing an electrochemical concrete surface treatment method.
