Application type cemented filling material containing superfine tail mud as well as preparation method and application thereof
The invention relates to an application type cemented filling material containing superfine tail mud as well as a preparation method and application thereof. The cemented filling material is prepared from the following raw materials: a cementing material, aggregate and water, wherein the cementing material comprises the following components in parts by weight: 10-30 parts of steel slag, 30-60 parts of mineral powder, 0-30 parts of gypsum and 5-20 parts of desulfurized fly ash; the aggregate comprises superfine tail mud; the mass ratio of the cementing material to the aggregate is 1: (4-7); the concentration of the slurry is 50-65%. A large amount of superfine tail mud is utilized, cement clinker is not doped, and good compressive strength capable of being industrially applied can be shown without adding an exciting agent, an early strength agent and other additives. According to the invention, the problem of stockpiling of solid wastes such as superfine tail mud, steel slag, mineral powder and desulfurization byproducts is reasonably solved, and the industrial application cost is greatly reduced.
本发明涉及一种含超细尾泥的应用型胶结充填料及其制备方法和应用，该胶结充填料的原料包括胶凝材料、骨料和水；其中，所述胶凝材料按重量份数计包括以下成分：钢渣10‑30份，矿粉30‑60份，石膏0‑30份，脱硫灰5‑20份；骨料包括超细尾泥；胶凝材料与骨料的质量之比为1:4‑7；料浆浓度为50‑65％。本发明利用了大量的超细尾泥，不掺入水泥熟料，并且无需添加激发剂、早强剂等外加剂即可显示出良好的可工业应用的抗压强度。本发明合理解决了超细尾泥、钢渣、矿粉以及脱硫副产物等固废堆存的难题，并极大地降低了工业应用成本。
