Nano micro-expansion inorganic grouting material and preparation method thereof
The invention discloses a nano micro-expansion inorganic grouting material and a preparation method thereof. The grouting material comprises a main material and a building additive, and the main material comprises building gypsum, slag powder, cement, nano silica powder, steel slag powder and fly ash; the building additive comprises a water reducing agent, a retarder, cellulose ether, a defoamingagent and redispersible latex powder. All the raw materials are mixed and stirred evenly in proportion to obtain the nano micro-expansion inorganic grouting material. According to the invention, inorganic materials such as slag powder, cement, nano silica powder, steel slag powder, fly ash and the like and related additives are added into industrial byproduct gypsum for modification; therefore, the nano micro-expansion inorganic grouting material has the advantages of micro-expansion, good fluidity, good cohesiveness, high consolidation rate, high early strength, high compressive and flexuralstrength, high water resistance, corrosion resistance, high fireproof grade, re-utilization of industrial solid wastes, low cost, easiness in construction, no pollution to human bodies and the environment and the like.
本发明公开了一种纳米微膨胀无机注浆材料及其制备方法。所述注浆材料包括主料及建筑外加剂，其中，主料包括建筑石膏、矿渣粉、水泥、纳米硅微粉、钢渣粉及粉煤灰；所述建筑外加剂，包括减水剂、缓凝剂、纤维素醚、消泡剂及可再分散性乳胶粉。将所有原料按比例混合搅拌均匀，即得纳米微膨胀无机注浆材料。本发明通过对工业副产品石膏添加矿渣粉、水泥、纳米硅微粉、钢渣粉、粉煤灰等无机材料和相关添加剂进行改性，使得本发明的纳米微膨胀无机注浆材料具有微膨胀、流动性好、粘结性好、固结率高、早期强度大、抗压与抗折强度大、耐水性强、耐腐蚀、防火等级高、工业固废再利用、成本低廉、易施工、对人体和环境无污染等优点。
