Abstract
The invention relates to the technical field of grouting materials, and discloses an acidic water glass grouting material which comprises the following components, by weight: 11-67 parts of water glass, 17-79 parts of an acid solution and 4-17 parts of water-soluble polyol. The invention also discloses a preparation method of the acidic water glass grouting material. The preparation method comprises the following steps: S1, weighing water glass, an acid solution and water-soluble polyol according to a ratio; S2, uniformly mixing the acid solution with water-soluble polyol to obtain a mixed solution; and S3, adding the water glass into the mixed solution in a stirring mode, and uniformly performing mixing, thereby obtaining the product. According to the acidic water glass grouting materialdisclosed by the invention, through the synergistic effect of the water-soluble polyhydric alcohol and the acid solution, the effects of better controlling the gelation process and the gelation time of the sodium silicate, improving the compressive strength, the stability and the viscosity of the acidic sodium silicate grouting material, reducing the brittleness of the grouting material and enhancing the acid resistance and the water resistance of the sodium silicate gel are achieved.
Description
technical field [0001] The invention relates to the technical field of grouting materials for construction, in particular to an acidic water glass grouting material and a preparation method thereof. Background technique [0002] Grouting is an engineering activity, which refers to using supporting mechanical equipment and adopting a reasonable grouting process to inject grout into the gaps, cracks, roadways or cavities of rocks and soils, so that the grout can be diffused, coagulated and hardened to reduce Improve the permeability of rock and soil, enhance its strength and stability, and achieve the purposes of rock and soil reinforcement, seepage prevention and water blocking. Commonly used grouting materials include cement-based grouting materials, epoxy resin grouting materials, phenolic resin grouting materials, polyurethane grouting materials and water glass grouting materials. [0003] Water glass is an aqueous solution of alkali metal silicate, usually referred to as...
