REPAIR METHOD FOR DAMAGED UNIT OF CONCRETE USING SALT REMOVAL SOLUTION

摘要

The present invention relates to a repair method for a damaged unit of concrete using a salt removal solution. According to the present invention, the repair method for a concrete structure includes: a surface treatment step of treating a surface of a damaged unit (10) of a concrete structure (A) damaged by sa a washing step of washing the surface-treated damaged unit (10) using water; a solution applying step of applying the salt removal solution on the damaged unit (10) and forming a solution application unit (20); a water applying step of applying the water on the surface of the solution application unit (20) after salt removal solution permeates the damaged unit (10) and forming a water application unit (30); a salt removal solution removing salt extracted to the surface of the damaged unit (10); and a mortar filling step of filling polymer mortar in the damaged unit (10) and having a mortar filling unit (40). The repair method for a concrete structure removes the salt of the damaged unit of the concrete using the salt removal solution and maintains strength of the concrete structure by filling the damaged unit with the polymer mortar. According to the present invention, the repair method removes chlorine from the concrete damaged by being exposed to a salt damage environment and restore the strength of the concrete structure by refilling the damaged unit with the mortar.;COPYRIGHT KIPO 2016
