Lepidolite lithium extraction slag-based cementing material and preparation method thereof
The invention discloses a lepidolite lithium extraction slag-based cementing material and a preparation method thereof, and belongs to the technical field of building materials. The lepidolite lithium extraction slag-based cementing material is prepared from lepidolite lithium extraction slag powder, cement and anhydrous sodium sulfate, and the preparation method comprises the following steps: carrying out ball milling on a lepidolite lithium extraction slag raw material, and uniformly mixing with the cement to obtain a lithium slag-cement system; and uniformly mixing the lithium slag-cement system with anhydrous sodium sulfate to obtain the lepidolite lithium extraction slag-based cementing material. According to the cementing material, the lepidolite lithium extraction slag is used as a main raw material, so that recycling, high-valued and reduction treatment of solid waste can be realized, the comprehensive utilization rate of the solid waste can be improved, the investment in the aspect of discharge management of the smelting slag solid waste can be reduced, and the industrial development requirements of national energy conservation, environmental protection and circular economy are highly met.
本发明公开了一种锂云母提锂渣基胶凝材料及其制备方法，属于建筑材料技术领域。锂云母提锂渣基胶凝材料由锂云母提锂渣粉、水泥和无水硫酸钠组成，其制备方法是：将锂云母提锂渣原料进行球磨后与水泥混合均匀，得到锂渣‑水泥体系；将锂渣‑水泥体系与无水硫酸钠混合均匀，得到锂云母提锂渣基胶凝材料。该胶凝材料以锂云母提锂渣为主要原料，能够实现固废的资源化、高值化和减量化处理，提高固体废弃物综合利用率，还能降低冶炼渣固废排放管理方面的投资，高度契合国家节能环保、循环经济的产业发展需求。
