Composite lithium slag-steel slag synergistic solid waste composite powder and preparation method thereof
The invention provides composite lithium slag-steel slag synergistic solid waste composite powder and a preparation method thereof, and belongs to the field of building materials. The solid waste composite powder comprises lithium slag A, lithium slag B, lithium slag C and carbon steel slag. The preparation method comprises the following steps: mixing the lithium slag A, the lithium slag B, the lithium slag C and the carbon steel slag, feeding the mixture into a tire vertical mill by adopting a conveying belt, and obtaining the 400-500-mesh composite lithium slag-steel slag synergistic solid waste composite powder through winnowing equipment under the mechanical force action of a millstone and a grinding roller. The problems that the gelatinization activity of the steel slag micro-powder is insufficient, and the stability is unqualified due to the fact that the steel slag micro-powder contains f-CaO are solved; and meanwhile, the composite lithium slag-steel slag synergistic solid waste composite powder is formed by grinding through a tire vertical mill and is used for cement and concrete, so that the use amount of cement can be reduced while the use amount of an admixture/admixture can be increased, the purpose of reducing carbon in the field of cementing materials is achieved, and the current industrial development requirements of energy conservation, environmental protection and circular economy are met.
本发明提供了一种复合锂渣‑钢渣协同固废复合粉及其制备方法，属于建筑材料领域。该固废复合粉包括锂渣A、锂渣B、锂渣C与碳钢钢渣。其制备方法是：将锂渣A、锂渣B、锂渣C与碳钢钢渣进行混合，采用输送带将上述混合物送入轮胎立磨，在磨盘与磨辊的机械力作用下，通过风选设备，获得400目～500目复合锂渣‑钢渣协同固废复合粉。本发明解决了钢渣微粉的胶凝活性不足，且含有f‑CaO导致安定性不合格等问题；同时本发明利用轮胎立磨粉磨形成复合锂渣‑钢渣协同固废复合粉用于水泥与混凝土，可以提高掺合料/混合材的用量替的同时，减少水泥用量，实现胶凝材料领域降碳减碳目的，符合当前节能环保、循环经济的产业发展要求。
