Refractory mortar based on vacuum aluminothermic reduction lithium slag and preparation method thereof
The invention relates to the field of novel materials for comprehensive utilization of industrial solid wastes, in particular to refractory mortar based on vacuum aluminothermic reduction lithium slag and a preparation method of the refractory mortar. The refractory mortar is prepared from the following raw materials in parts by weight: 24-56 parts of vacuum aluminothermic reduction lithium slag powder, 10-20 parts of micro aggregate, 20-35 parts of quartz sand, 2-5 parts of an acid activator, 0.5-1 part of a surfactant and 11.5-15 parts of water. The preparation method comprises the following steps: S1, sequentially adding an acidic activator and a surfactant into water, and uniformly mixing to obtain a mixed solution; s2, adding the vacuum aluminothermic reduction lithium slag powder and the micro aggregate into the mixed solution, and uniformly mixing to obtain slurry; and S3, adding siliceous tailing sand into the slurry, and uniformly mixing to obtain the refractory mortar based on the vacuum aluminothermic reduction lithium slag. The refractory mortar which is good in fluidity, high in strength and resistant to high temperature is prepared, the feasibility of building material utilization of the vacuum aluminothermic reduction lithium slag is verified, and good economic benefits and social benefits are achieved.
本发明涉及工业固体废弃物综合利用的新型材料领域，具体是涉及一种基于真空铝热还原锂渣的耐火砂浆及其制备方法。所述耐火砂浆由以下重量份的原料制成：真空铝热还原锂渣粉24～56份、微集料10～20份、石英砂20～35份、酸性激发剂2～5份、表面活性剂0.5～1份、水11.5～15份。由以下步骤制备而成：S1：将酸性激发剂、表面活性剂依次加入水中混合均匀，得到混合溶液；S2：将真空铝热还原锂渣粉、微集料加入混合溶液中混合均匀，得到浆体；S3：将硅质尾矿砂加入浆体中混合均匀，即得基于真空铝热还原锂渣的耐火砂浆。本发明制备了一种流动性好、强度高、耐高温的耐火砂浆，验证了对真空铝热还原锂渣进行建材化利用的可行性，具备良好的经济效益和社会效益。
