Method for enhancing concrete duability using chloride measuring agent, alkali recovery agent, impurities remover and impurity repellent

摘要

The present invention comprises the steps of: (1) checking whether a concrete structure is damaged by chloride using a chloride measuring agent; (2) cleaning the damaged surface of the damaged concrete structure using a grinding or rock drill, and washing with water; (3) applying an alkali recovery agent to the surface of the concrete structure; (4) applying an impurity removing agent to the surface of the concrete structure in which the alkali recovery agent has penetrated, and infiltrating the impurity removing agent into the interior of the concrete structure; (5) applying water to the surface of the concrete structure to remove reactants and impurities with the impurity removing agent; And (6) applying an impurity repenetration inhibitor to the surface of the concrete structure; it relates to a method for improving durability of a concrete structure including.
