Composite grouting reinforcement material and preparation method thereof
The invention provides a preparation method of a composite grouting reinforcement material. The method comprises the following steps: providing cement, quartz powder and cellulose, and mixing to obtain a component A; providing calcium fluoroaluminate, calcium oxide, dehydrated gypsum, silicon micro-powder and a water reducing agent, and mixing to obtain a component B; premixing the component A and the component B to obtain premixed powder; and providing water, and mixing the water with the premixed powder to obtain the composite grouting reinforcement material, wherein the mass percentage ratio of the cement to the quartz powder to the cellulose to the calcium fluoroaluminate to the calcium oxide to the dehydrated gypsum to the silicon micro-powder to the water reducing agent is (60-67%): (5-16%): (0.2-0.5%): (8-19%): (5-15%): (5-16%): (5-17%): (0.2-0.5%), and a mass ratio of the water to the premixed powder is 100: (40-80). The composite grouting reinforcement material disclosed by the invention has the advantages of better permeability, large flowability, groutability, adjustable setting time, high compressive strength and strong adaptability to coal and rock masses.
本发明提供一种复合型注浆加固材料的制备方法，包括：提供水泥、石英粉、纤维素，混合得到A组份；提供氟铝酸钙、氧化钙、脱水石膏、硅微粉、减水剂，混合得到B组份；将所述A组份与所述B组份预混合得到预混粉料；提供水，将所述水与所述预混粉料混合，得到复合型注浆加固材料；所述水泥、石英粉、纤维素、氟铝酸钙、氧化钙、脱水石膏、硅微粉、减水剂的质量百分比为60～67％：5～16％：0.2～0.5％：8～19％：5～15％：5～16％：5～17％：0.2～0.5％；水与所述预混粉料的质量比为100：40～80，本发明的复合型注浆加固材料对煤岩体有较好的渗透性，大的流动性，可注性，凝结时间可调，抗压强度高，适应性强。
