METHOD FOR REPAIR AND SUPPRESS OF STEEL CORROSION BY USING HIGH ALKALI ORGANIC CORROSION INHIBITOR AND CORROSION INHIBITION SURFACE COATING COMPOSITION HAVING CORROSION PERFORMANCE AND FIXING CARBON DIOXIDE AND CHLORINE ION

摘要

The present invention is to provide a method for repairing and inhibiting corrosion of a reinforcing bar using a high alkali organic corrosion inhibitor and a coating material having corrosion resistance properties and fixing properties of carbon dioxide and chlorine ion. The method comprises a step of determining corrosion of a reinforcing bar whether corrosion, a crack, or separation is generated on the reinforcing bar of a reinforced concrete structure; a step of repairing and inhibiting the corrosion of the reinforcing bar by coating a high alkali organic corrosion inhibitor and coating a water-based surface reinforcing agent and an anti-corrosion surface coating material having fixing properties of carbon dioxide and chlorine ion, when the corrosion, the crack, or the separation is not generated on the reinforcing bar; a step of repairing the corrosion of the reinforcing bar by applying a high alkali organic corrosion inhibitor, carrying out a process for applying mortar on the corroded reinforcing bar area, and applying a water-based surface reinforcing agent, an anti-corrosion surface recovering material having the fixing properties of carbon dioxide and chlorine ion, when the corrosion, the crack, or the separation is generated. The method removes a cause of deterioration in an active manner by fixing carbon dioxide and chlorine ions penetrating into a reinforced concrete structure and protects a reinforced concrete structure, which may lower durability due to carbonation and a damage caused by salt, by using in combination with the high alkali organic corrosion inhibitor.
