Method for brushing nitrite solution on surface of reinforced concrete to inhibit rusting
The invention discloses a method for brushing a nitrite solution on the surface of reinforced concrete to inhibit rusting. The method is characterized by including: finding a rusty position, and frosting the surface of the rusty position; using a nitrite saturated water solution to moisten the frost surface to form a water film on the frost surface; covering the frosted surface with a sponge sufficiently absorbing the nitrile saturated water solution; covering the sponge with waterproof felt cloth, and hermetically fixing the edge around the waterproof felt cloth to the surface of a reinforced concrete structure; pressing a weight on the waterproof felt cloth to enable thickness of the sponge to be compressed by more than one third, and maintaining for 2-3 weeks. The method has the advantages that the method is simple, convenient and effective in operation, and permeation velocity of the nitrile solution in concrete can be increased, so that the nitrile solution is enabled to serve as a permeable rusting inhibitor to be externally coated on the surface of the reinforced concrete structure, is especially suitable for large-area antirust repairing of the reinforce concrete structure and has no obvious negative influence on structural performance of a concrete body.
