Abstract

The invention discloses a water-borne high permeability crystal waterproof hardening agent. The proof hardening agent comprises the following components in percent by weight: 20 to 40 percent of alkali metal silicate, 0.25 to 1 percent of an early strength agent, 1 to 6 percent of a catalyst, 0 to 0.5 percent of a surfactant, 1 to 4 percent of a hardening accelerator, 0.5 to 2 percent of water soluble high molecular polymer, 0 to 8 percent of organic silicon, and water for the surplus. The waterproof hardening agent is moderate in cost, can realize complete localization, higher in penetration depth, higher in hardness after being reacted with substance in concrete, and higher in hydraulic pressure resistance capacity.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a water-based high-permeability crystalline waterproof hardener. Background technique [0002] Leakage is one of the common main diseases of concrete buildings. Leakage is very harmful to concrete buildings. One is that leakage will cause corrosion damage to concrete. The so-called dissolution refers to the leaching erosion of concrete by seepage water. As we all know, the hydration products of cement in concrete mainly include calcium silicate hydrate, calcium aluminate hydrate, calcium ferric aluminate hydrate and calcium hydroxide, and sufficient calcium hydroxide is the coagulation and crystallization of other hydration products. guarantee. Among the above hydration products, calcium hydroxide has a higher solubility in water. Under normal circumstances, saturated calcium hydroxide solution exists in the pores of concrete. Once leakage occurs, the seepage wate...
