Micro-expansive and strong-impermeability cement-based grouting material and preparation method thereof
The invention discloses a cement-based grouting material with micro-expansion and strong impermeability. The material comprises the following components in parts by weight: 90-113 parts of a matrix material, 5-12 parts of a composite activator and 95-125 parts of water, wherein the base material comprises the following components in parts by weight: 50-80 parts of Portland cement clinker, 5-20 parts of silica fume, 13-22 parts of silicon-calcium slag, 20-45 parts of coal-fired slag and 5-13 parts of bentonite; and the composite activator comprises the following components in parts by weight: 10-35 parts of solid sodium silicate, 8-30 parts of magnesium oxide and 5-19 parts of calcium sulfate. The invention also discloses a preparation method of the cement-based grouting material with micro-expansion and strong impermeability. The cement-based grouting material is obviously superior to P.O42.5 cement in the aspects of single performance and comprehensive performance, particularly has relatively high shrinkage resistance and impermeability, is more suitable for lining anti-seepage treatment of underground engineering, and has the advantages of stable volume, impermeability, durability, adjustable setting time, economy, environmental protection and the like.
本发明公开了一种微膨胀、强抗渗的水泥基注浆材料，包括以下组分及其重量份数：基体材料90‑113份、复合激发剂5‑12份以及水95‑125份，其中基体材料包括以下组分及其重量份数：硅酸盐水泥熟料50‑80份、硅灰5‑20份、硅钙渣13‑22份、燃煤炉渣20‑45份以及膨润土5‑13份；复合激发剂包括以下组分及其重量份数：固体硅酸钠10‑35份、氧化镁8‑30份以及硫酸钙5‑19份。本发明还公开了一种微膨胀、强抗渗的水泥基注浆材料的制备方法。本发明水泥基注浆材料无论在单一性能上，还是在综合性能上，都明显的优于P·O42.5水泥，尤其是较高的抗收缩与抗渗性能，更加适用于地下工程的衬砌防渗治理，具有体积稳定、抗渗耐久、凝结时间可调和经济环保等优点。
