Method for producing clinker-free cement from large-mixing-amount lepidolite slag
The invention discloses a method for producing clinker-free cement from large-dosage lepidolite slag, and belongs to the technical field of industrial waste residue utilization and cement building materials. The preparation method comprises the following steps: weighing 35-45% by mass of lepidolite slag, 25-35% by mass of steel plant slag, 15-25% by mass of steel plant steel slag and 5-8% by mass of gypsum, uniformly mixing the weighed lepidolite slag, steel plant slag, steel plant steel slag and gypsum, adding a grinding aid, and grinding to obtain the clinker-free cement. The cement produced by the method disclosed by the invention is high in strength and stable in performance, a large amount of waste lepidolite slag is treated for the society while the production cost is reduced, and the economic and social benefits are good; and on the basis that 40% of lepidolite slag is doped into 1 million tons of cement per year, 0.4 million tons of lepidolite slag can be consumed, so that land resources occupied by stacking or landfilling of the lepidolite slag are greatly saved, and the environmental protection pressure is reduced.
本发明公开了一种大掺量锂云母渣生产无熟料水泥的方法,属于工业废渣利用及水泥建材技术领域。本发明按质量百分比称取锂云母渣35%‑45%、钢厂矿渣25%‑35%、钢厂钢渣15%‑25%、石膏5%‑8%,然后将称好的锂云母渣、钢厂矿渣、钢厂钢渣、石膏混合均匀,加入助磨剂进行粉磨即得无熟料水泥。本发明方法生产的水泥强度高、性能稳定,在降低了生产成本的同时,为社会处理了大量的废弃锂云母渣,经济及社会效益良好;按年产100万吨水泥掺入40%的锂云母渣计算,可消纳40万吨锂云母渣,大大节省堆放或填埋锂云母渣所占用的土地资源,降低了环保压力。
