Low-viscosity high-strength cement-based grouting material and preparation method thereof
The invention discloses a low-viscosity high-strength cement-based grouting material and a preparation method thereof. The grouting material comprises the following components: 300-600 parts of a gelling material with volcanic ash characteristics, 0.2-0.6 part of a micro-nano coagulant, and a water reducing agent accounting for 0.25-2% of the mass of the gelling material, and the water-binder ratio is 0.4-0.8. Wherein the cementing material with the volcanic ash characteristic comprises Portland cement and modified microbeads. The preparation method comprises the following step: uniformly mixing the cementing material with the volcanic ash characteristics and the micro-nano coagulation accelerator. And then adding a mixed solution formed by the water reducing agent and water, and uniformly stirring to obtain the cement-based grouting material. According to the invention, the water cement ratio of the cement paste is reduced, the strength of set cement is ensured, the viscosity of the cement paste is reduced, and the groutability is improved.
本发明公开一种低粘高强度水泥基注浆材料及制备方法，所述注浆材料包括如下组分：具有火山灰特性的胶凝材料300~600份、微纳促凝剂0.2~0.6份、所述胶凝材料质量0.25~2%的减水剂、水胶比为0.4~0.8。其中：所述具有火山灰特性的胶凝材料包括硅酸盐水泥和改性微珠。所述制备方法包括如下步骤：将所述具有火山灰特性的胶凝材料和微纳促凝剂混合均匀。然后加入所述减水剂和水形成的混合液，搅拌均匀即得所述水泥基注浆材料。本发明在降低水泥浆水灰比，保证水泥石强度的同时，降低了水泥浆的粘度，提高了可注性。
