Abstract

The invention discloses a formula and a preparation method of an impermeable waterproof concrete repairing agent. The formula comprises sodium silicate, sodium carbonate, potassium metaaluminate, propylene glycol, sodium dodecyl sulfonate, octanol polyethylene ether and distilled water. The method comprises the following steps: 1, respectively dissolving sodium silicate, potassium metaaluminate, sodium carbonate and sodium dodecyl sulfonate in one part of distilled water to form four solutions; 2, adding the above prepared potassium metaaluminate solution into the above prepared sodium silicate solution; 3, adding the above prepared sodium carbonate solution into a solution obtained in step 2; 4, adding propylene glycol into a solution prepared in step 3; 5, adding isooctyl alcohol polyethylene ether into the above prepared sodium dodecyl sulfonate solution; and 6, mixing a solution prepared in step 5 with a solution prepared in step 4, and uniformly stirring. The impermeable waterproof concrete repairing agent provides a simple, rapid, efficient, reliable and economic protection measure for the durability of a concrete structure.

Description

technical field [0001] The invention relates to a formula and a preparation method of a concrete anti-seepage and waterproof restoration agent, belonging to the field of concrete waterproofing. Background technique [0002] During the construction and use of concrete, on the one hand, cracks are prone to occur due to the material or the use environment. For concrete structures or components in corrosive media or high humidity environments, it will cause corrosion of the steel bars in the concrete and affect the durability of the structure. On the other hand, with the increase of the service life, the concrete is aging day by day, coupled with improper use and maintenance, it is corroded by various harmful gases or corrosive media all the year round, and the concrete structure or components will also be damaged. [0003] Aggressive media to concrete include acid, alkali, salt, pressure, flowing water, etc. Especially concrete with cracks or cracks will age faster in aggressi...
