High-performance cement-silica sol grouting material and preparation method thereof
The invention relates to the technical field of grouting materials, in particular to a high-performance cement-silica sol grouting material and a preparation method thereof. The high-performance cement-silica sol grouting material comprises a component A and a component B. The component A comprises the following raw materials in parts by weight: 20-50 parts of Portland cement; 20 to 70 parts of water; 0.6 to 3.2 parts of a water reducing agent; the component B is prepared from the following raw materials in parts by weight: 30 to 60 parts of nano silica sol; 2-10 parts of a curing agent; 2-8 parts of inorganic fiber; 1.2-6 parts of an early strength agent and 10-50 parts of water. The grouting material prepared by the invention is high in strength, short in setting time, low in viscosity, good in groutability, strong in seepage force, good in water resistance, excellent in impermeability, high in retention rate and not easy to wash off; small cracks can be injected; the long-term durability is high, plugging of rock mass water seepage cracks and structural body cement paste cracks can be efficiently completed, and environmental protection is achieved.
本发明涉及灌浆料技术领域，具体涉及一种高性能的水泥‑硅溶胶灌浆料及其制备方法。所述的高性能的水泥‑硅溶胶灌浆料，包括A组分和B组分，所述A组分包括以下重量份的原料：硅酸盐水泥20‑50份；水20‑70份；减水剂0.6‑3.2份；所述B组分包括以下重量份的原料：纳米硅溶胶30‑60份；固化剂2‑10份；无机纤维2‑8份；早强剂1.2‑6份，水10‑50份。本发明所制得的灌浆料强度高，凝结时间快，粘度低，可灌性好，强渗透力，耐水性好，抗渗性极好，具有高留存率，不易冲失；可注入微小裂隙；长期耐久性高，能够高效的完成岩体渗水裂隙及结构体水泥浆裂隙的封堵，及绿色环保等优点。
