METHOD FOR REMOVING CORROSIVE ANIONS FROM THE PORE SOLUTIONS OF POROUS SOLIDS USING ZINC

摘要

The invention relates to a method for removing corrosive anions from the pore solutions of porous solids, e.g., concrete or brick walls and components, the method being characterized in that a water-based coating containing zinc is applied to the porous solid or the solid is impregnated with the coating, whereupon the corrosive anions in the pore solution are allowed to migrate to or into the coating and/or are caused to migrate to or into the coating containing zinc in order to form a compound there with the zinc, the compound being insoluble or poorly soluble in water.
