Modified lithium tailing slag composite cementing material and preparation method thereof
The invention provides a modified lithium tailing slag composite cementing material and a preparation method thereof. The modified lithium tailing slag composite cementing material comprises 60-70 parts of modified lithium tailing slag; 20 to 30 parts of cement clinker; 0.5 to 1 part of calcium lignosulphonate; and 0.2 to 1 part of rare earth. According to the modified lithium tailing slag composite cementing material disclosed by the invention, the environment pollution caused by the lithium tailing slag is avoided by using the modified lithium tailing slag, and the composite cementing material formed by the modified lithium tailing slag, the cement clinker, the calcium lignosulphonate and the rare earth has the advantages that the durability is high; and then the lithium tailings are processed through a cementing material and can be used for road, bridge, road, industrial and civil building engineering construction, so that the utilization rate of the lithium tailings can be improved, the ecological environment is prevented from being influenced by direct burying of the lithium tailings through soil, and building resources such as natural cement are saved.
本发明提供一种改性锂尾矿渣复合胶凝材料及其制备方法，包括改性锂尾矿渣60份～70份；水泥熟料20～30份；木钙0.5份～1份；稀土0.2份～1份。本发明中的改性锂尾矿渣复合胶凝材料通过使用改性锂尾矿渣，避免了锂尾矿渣对环境进行污染，并且通过改性锂尾矿渣、水泥熟料、木钙以及稀土形成的复合胶凝材料，然后通过胶凝材料进行加工可用于道路、桥梁、道路、工业及民用等建筑工程建设，从而能够使得锂尾矿渣的利用率得到提升，避免其直接通过土壤掩埋影响生态环境，并且节约了天然水泥等建筑资源。
