High-performance concrete anti-corrosion reinforcing agent, preparation method and application
The invention discloses a high-performance concrete anti-corrosion reinforcing agent, a preparation method and application, and belongs to the field of concrete additives. The high-performance concrete anti-corrosion reinforcing agent is prepared from a modified nano material with a filling effect, alkyl alcohol amine and a hydroxyl compound, the modified nano material is a nano material of which the surface is treated by an organic modifier; and the organic modifier is organosiloxane or organic carboxylic acid or a combination of the organosiloxane and the organic carboxylic acid. The organic siloxane is connected with the nano material through a silanol bond, and the organic carboxylic acid is physically adsorbed on the surface of the nano material. Through combination of a modified nano material and an alcohol amine hydration regulation and control material, the microstructure of the concrete is optimized and improved, the pore compactness of the concrete can be effectively optimized and improved, the corrosion resistance, freezing resistance and carbonization resistance of the concrete are realized, and the durability of the concrete is achieved.
