Artificial aggregate based on lithium slag, preparation method thereof and asphalt mixture
The invention discloses an artificial aggregate based on lithium slag, a preparation method thereof and an asphalt mixture, the artificial aggregate based on the lithium slag comprises the lithium slag, an alkali activator and a cementing material, the weight ratio of the lithium slag to the cementing material is (1.5-3.0): 1, and the ratio of the volume of the alkali activator to the total weight of the lithium slag and the cementing material is (0.28-0.32) ml: 1g; the alkali activator comprises-OH and-SiO3, the content of the-OH is 2.0 mol/L to 3.2 mol/L, and the content of the-SiO3 is 3.6 mol/L to 4.7 mol/L. According to the method, the utilization rate of the lithium slag can be increased, the use proportion of natural aggregate in the asphalt mixture is reduced, energy consumption and carbon emission in the production process of the asphalt mixture are reduced, and sustainable development of the society is achieved.
本发明公开了一种基于锂渣的人造集料、其制备方法及沥青混合料，一种基于锂渣的人造集料，包括锂渣、碱激发剂和胶凝材料，其中，所述锂渣与所述胶凝材料的重量比为(1.5～3.0)：1，所述碱激发剂的体积与所述锂渣和所述胶凝材料的总重量比为(0.28～0.32)ml：1g；所述碱激发剂包括‑OH和‑SiO3，其中，所述‑OH的含量为2.0mol/L～3.2mol/L，所述‑SiO3的含量为3.6mol/L～4.7mol/L。本发明能够提高锂渣的利用率，节约沥青混合料中天然集料的使用比例，降低沥青混合料生产过程中的能耗与碳排放，实现社会的可持续发展。
