Embodiment 1
[0051] Inorganic grouting material that can prevent water and strengthen structures
[0052] Component A (parts by weight): 4 parts of potassium silicate aqueous solution (30%), 3 parts of sodium silicate aqueous solution (40%), 1.5 parts of dispersant stearamide, 0.2 part of antifoaming agent dimethyl silicone oil, 10 parts of water share;
[0053] Component B (parts by weight): 0.2 parts of polycarboxylate high-efficiency water reducer, 20 parts of high-performance superfine cement-based grouting material, 8 parts of alkaline mineral powder, 0.5 parts of silica fume, 3 parts of fly ash, flocculant poly 0.6 parts of acrylamide, 0.5 parts of expansion agent magnesium oxide, and 10 parts of water.
[0054] The inorganic grouting material of this embodiment has a fast solidification speed and can be used for cavities and gaps with large water seepage.
Embodiment 2
[0056] Inorganic grouting material that can prevent water and strengthen structures
[0057] Component A (parts by weight): 3 parts of potassium silicate aqueous solution (30%), 2 parts of sodium silicate aqueous solution (40%), 1 part of dispersant stearamide, 0.1 part of antifoaming agent dimethyl silicone oil, 13 parts of water share;
[0058] Component B (parts by weight): 0.2 parts of polycarboxylate high-efficiency water reducer, 25 parts of high-performance superfine cement-based grouting material, 9 parts of alkaline mineral powder, 0.7 parts of silica fume, 2 parts of fly ash, flocculant poly 0.6 parts of acrylamide, 0.5 parts of magnesium oxide as an expansion agent, 1 part of citric acid as a retarder, and 13 parts of water.
[0059] Compared with Example 1, the inorganic grouting material in this embodiment slows down the solidification time, and can target cavities and cracks with small water seepage and high penetration requirements.
Embodiment 3
