Superfine cement-based composite cementing material for underground mine filling and preparation method of superfine cement-based composite cementing material
The invention relates to the field of cementing materials, in particular to a superfine cement-based composite cementing material for underground mine filling and a preparation method of the superfine cement-based composite cementing material. The superfine cement-based composite cementing material for underground mine filling comprises the following raw materials in parts by mass: 50-70 parts of superfine cement, 20-30 parts of tailing sand, 10-15 parts of modified desulfurized gypsum, 5-12 parts of fly ash, 8-16 parts of modified resin, 0.5-1.5 parts of a reinforcing agent, 0.4-1.2 parts of a water reducing agent, 5-15 parts of a fiber material and 40-60 parts of water. The superfine cement-based composite cementing material prepared by the invention not only has excellent mechanical strength and relatively low shrinkage rate, but also can ensure good water resistance and permeability resistance, so that the diversity performance requirements of the existing mining industry on mine filling materials are effectively met, the application environment of the superfine cement-based composite cementing material is expanded, and the application prospect is wide. And the method has a very excellent application prospect.
本申请涉及胶结材料领域，尤其涉及一种用于地下矿山充填的超细水泥基复合胶结材料及其制备方法。用于地下矿山充填的超细水泥基复合胶结材料，以质量份计，原料为：超细水泥50～70份，尾矿砂20～30份，改性脱硫石膏10～15份，粉煤灰5～12份，改性树脂8～16份，增强剂0.5～1.5份，减水剂0.4～1.2份，纤维料5～15份，水40～60份。本申请制得的超细水泥基复合胶结材料不仅具有优异的力学强度，较低的收缩率，还能够保证良好的耐水放渗透性能，从而有效满足现有采矿业对于矿山填充材料的多样性性能需求，扩展了超细水泥基复合胶结材料的应用环境，具有十分优异的应用前景。
