A disclosed alkali-activated grouting material is prepared from the following raw materials in parts by weight: 40 to 60 parts of slag powder, 30 to 40 parts of water glass, 100 to 200 parts of high-iron sulphoaluminate cement, 20 to 30 parts of sodium bentonite, 20 to 30 parts of lithium carbonate, 10 to 20 parts of citric acid, 10 to 20 parts of graphene oxide, 20 to 60 parts of sodium hydroxide, 10 to 30 parts of sodium alginate and 20 to 40 parts of silicon dioxide. Sodium hydroxide and sodium alginate are added, so that the slag powder can be excited to form a novel gel material, and the breaking strength and the compressive strength of the novel gel material are improved.
本发明公开了一种碱激发灌浆料，包括以下重量份计的原料：矿渣粉40‑60份、水玻璃30‑40份、高铁硫铝酸盐水泥100‑200份、钠基膨润土20‑30份、碳酸锂20‑30份、柠檬酸10‑20份、氧化石墨烯10‑20份、氢氧化钠20‑60份、海藻酸钠10‑30份、二氧化硅20‑40份。氢氧化钠和海藻酸钠的加入能够激发矿渣粉，形成一种新型凝胶材料，提高本发明的抗折强度和抗压强度。
