Alkali-activated phosphorus slag paste filling material and preparation method thereof
The invention discloses an alkali-activated phosphorus slag paste filling material and a preparation method thereof, and belongs to the technical field of paste filling materials. The filling body cementing material comprises 75-85% of ground phosphorus slag and 15-25% of mineral slag, the mass concentration of the filling body cementing material is 82%, the use amount of the alkali-activated material red mud is 10-40% of the total mass of the cementing material, the use amount of NaOH is 4-8% of the total mass of the cementing material, the cementing material and the alkali-activated material red mud are mixed and stirred uniformly, then the tailings are added and stirred, finally, a NaOH and water mixed solution is poured, and the filling body cementing material is obtained. And the filling body material slurry can be prepared. Cement can be effectively replaced by utilizing the pozzolanic activity and the micro aggregate filling effect of the phosphorus slag micro powder, the utilization rate of solid waste is increased, and the strength requirement and the fluidity requirement of a controllable low-strength material are also met. The slurry can be applied to the fields of goaf backfilling and filling mining, and has certain practical significance.
一种碱激发磷渣膏体充填材料及其制备方法，属于膏体充填材料技术领域。充填体胶凝材料为磨细磷渣75‑85％，矿渣15‑25％，质量浓度为82％，碱性激发材料赤泥用量为胶凝材料总质量的10‑40％，NaOH用量为胶凝材料总质量的4‑8％，将胶凝材料和碱激发材料赤坭混合搅拌均匀，再加入尾砂搅拌，最后倒入NaOH与水混合溶液，可制得充填体材料料浆。本发明利用磷渣微粉的火山灰活性和微集料填充效应，可以有效替代水泥，提高了固体废弃的利用率，也达到了可控低强度材料的强度要求和流动性要求。该料浆可应用到采空区回填及充填开采领域，具有一定的实用意义。
