PURPOSE: To obtain a deterioration-preventing agent which has good adhesion to a concrete structure for a long time and has an excellent antioxidation effect and the like by dispersing a fluorocarbon resin, copper-titanium-nickel powder, and uncured portland cement or mortar in water. CONSTITUTION: This deterioration-preventing agent for a concrete structure is produced by dispersing at least a fluorocarbon resin, copper-titanium-nickel powder, and uncured portland cement or mortar in water. Especially, it is preferable to compound the fluorocarbon resin and the copper-titanium-nickel powder at 1:3 to 3:1 weight ratio in order to obtain a corrosion-preventing effect after coating and hardening. A silane-based water-repellent agent increase the water resistance after hardening. A water-soluble polymer improves the workability, holding property and resistance against blending. Various kinds of surfactants such as anion, cation and amphoteric surfactants are available, however, at the time of adding a surfactant, its foaming tendency should carefully be considered. |
