Lithium slag-based artificial aggregate and preparation method thereof
The invention discloses a lithium slag-based artificial aggregate and a preparation method thereof, and belongs to the technical field of building materials. The lithium slag-based artificial aggregate is prepared from the following raw materials in parts by weight: 180-295 parts of an exciting agent, 5-20 parts of a modifying agent and 700-800 parts of lithium slag through balling and maintenance, wherein the exciting agent comprises at least one of cement, mineral powder and quick lime; the modifier comprises soluble phosphate and bentonite; and the lithium slag is ground. The lithium slag is ground to a certain specific surface area, so that the activity of the lithium slag is excited, and the strength of the artificial aggregate is improved; the modifier is further used for improving the water resistance of the artificial aggregate prepared from the lithium slag, the softening coefficient of the artificial aggregate is increased, meanwhile, leaching of alkali metal and sulfate ions is reduced, and the application way of the lithium slag is widened.
本发明公开了一种锂渣基人造骨料及其制备方法，属于建筑材料技术领域。该锂渣基人造骨料是将包括如下重量份的原料：激发剂180‑295份、改性剂5‑20份、锂渣700‑800份，经成球、养护后制得；其中，激发剂包括水泥、矿粉和生石灰中的至少一种；改性剂包括可溶性磷酸盐和膨润土；锂渣经过粉磨处理。本发明通过将锂渣粉磨至一定的比表面积，激发了锂渣活性，提高人造骨料的强度；进一步利用改性剂改善锂渣制备的人造骨料的耐水性，提高其软化系数，同时降低了碱金属以及硫酸根离子的浸出，拓宽了锂渣的应用途径。
