Lithium slag-based compound superfine composite mineral powder production formula and production process
The invention discloses a lithium slag-based compound superfine composite mineral powder production formula and production process, and the lithium slag-based compound superfine composite mineral powder production formula comprises the following raw materials in parts by weight: 200-300 parts of lithium slag, 30-50 parts of granulated water slag, 20-30 parts of slaked lime, 15-30 parts of fly ash, 10-15 parts of a dispersant and 40-60 parts of a surfactant. Lithium slag is ground into powder through a vertical mill, then dried and separated and screened through a cyclone separator to obtain superfine lithium slag powder, the lithium slag, granulated water slag, slaked lime and fly ash are subjected to an activation reaction through a dispersing agent and a surface activating agent, the porosity is reduced, the specific surface area is increased, and therefore the water absorption rate is reduced when the lithium slag serves as an admixture; according to the present invention, the superfine powder is added, such that the mutual cohesion among the cement particles is reduced, the hydration reaction is easily performed, the water consumption is reduced, the workability and the pumpability are improved, the superfine powder is filled in the cement slurry gap so as to change the pore structure, and the concrete compactness is improved.
本发明公开了一种基于锂渣复配超细复合矿粉生产配方及生产工艺，以重量份计，其原料组成包括：锂渣200‑300份、粒化水渣30‑50份、熟石灰20‑30份、粉煤灰15‑30份、分散剂10‑15份和表面活化剂40‑60份。锂渣通过立磨机研磨成粉末，然后烘干通过旋风分离器进行分离筛选得到超细锂渣粉末，锂渣、粒化水渣、熟石灰和粉煤灰通过分散剂和表面活化剂对粉末进行活化反应，减小孔隙率，提高比表面积，从而作为掺合料时降低吸水率，使得水泥颗粒之间的相互粘聚减少，利于水化反应的进行，同时减少了用水量，改善和易性和可泵性，超细粉末填充在水泥浆空隙中，改变了孔结构，提高了混凝土的密实度。
