Functional early strength cement-based grouting material and preparation method thereof
The invention belongs to the field of special cement-based building materials, and discloses a functional early-strength cement-based grouting material, which is prepared from the following components in parts by weight: 70 to 85 parts of superfine special cement, 10 to 25 parts of mineral admixture, 90 to 105 parts of superfine tailing sand, 0.8 to 1.5 parts of water reducing agent, 0.3 to 0.6 part of rheological additive, 1.0 to 1.6 parts of reinforcing agent, 0.1 to 0.6 part of seepage-proofing agent and 0.2 to 0.7 part of corrosion inhibitor. The components are uniformly mixed, then water is added according to the water-material ratio of 0.26-0.28, stirring is performed to form uniform slurry, and grouting construction can be performed. The obtained cement-based grouting material has the characteristics of high groutability, micro-expansion, early strength, high strength, permeability resistance, rust resistance and the like, is suitable for grouting construction of various gaps and pore channels, consumes solid waste, belongs to an environment-friendly building material, and has wide popularization and application prospects.
本发明属于特种水泥基建筑材料领域，公开了一种功能型早强水泥基注浆料，由下列组分按重量份数配制而成：超细特种水泥70‑85份、矿物掺合料10‑25份、特细尾矿砂90‑105份、减水剂0.8‑1.5份、流变助剂0.3‑0.6份、增强剂1.0‑1.6份、防渗剂0.1‑0.6份、阻锈剂0.2‑0.7份。将上述各组分混合均匀，然后按照0.26‑0.28的水料比加水搅拌形成均匀浆体，即可进行注浆施工。本发明所得水泥基注浆料具有高可注性、微膨胀、早强高强、抗渗阻锈等特点，适用于各种缝隙和孔道注浆施工，并且消纳固废，属环境友好型建筑材料，具有广泛的推广应用前景。
