Method for preparing mixed fiber reinforced cemented lithium feldspar tailing filling body doped with lithium slag
The invention provides a method for preparing a mixed fiber reinforced cemented lithium feldspar tailing filling body doped with lithium slag. The method comprises the following steps: step S1, respectively carrying out ball milling and drying on fly ash, lithium feldspar tailings, lithium slag and slag powder; s2, controlling the mass ratio of the cementing material to the filling aggregate to be 1: 6, firstly performing dry stirring on the cementing material, the filling aggregate, slag powder, desulfurized gypsum, polypropylene fibers and glass fibers for a period of time, then adding water, and performing stirring for a period of time until the polypropylene fibers and the glass fibers are fully dispersed to obtain slurry; and S3, the slurry is poured into a mold and cured, and the mixed fiber reinforced cemented lithium feldspar tailing filling body doped with the lithium slag is obtained. The prepared filling body has high strength and high toughness.
本发明提供一种制备掺锂渣的混合纤维增强胶结锂长石尾砂充填体的方法，包括：步骤S1、将粉煤灰、锂长石尾砂、锂渣、矿渣粉分别进行球磨并干燥；步骤S2、控制胶凝材料与填充骨料质量比为1∶6，将胶凝材料、填充骨料、矿渣粉、脱硫石膏、聚丙烯纤维和玻璃纤维先干搅拌一段时间，然后再加入水搅拌一段时间，直至聚丙烯纤维和玻璃纤维充分分散，得到料浆；步骤S3、将料浆倒入模具中并进行养护，即得到掺锂渣的混合纤维增强胶结锂长石尾砂充填体。本发明制备的充填体具有高强度与高韧性。
