Lithium slag-based composite cementing material and preparation method thereof
The embodiment of the invention provides a lithium slag-based composite cementing material and a preparation method thereof, and relates to the field of composite materials. The preparation method of the lithium slag-based composite cementing material comprises the following steps that S100, lithium slag and an inorganic acid solution are mixed and then activated, an activated material is obtained, and the component of the lithium slag comprises aluminosilicate; s200, an alkaline substance and the activated material are mechanically mixed, a modified material is obtained, the pH of the modified material is 7-10, then the modified material is dried, and modified powder is obtained; and S300, grinding the modified powder and auxiliary materials to obtain the lithium slag-based composite cementing material. The preparation method provided by the invention is high in lithium slag mixing amount and relatively low in cost, and the prepared lithium slag-based composite cementing material is also relatively high in compressive strength.
本申请实施例提供一种锂渣基复合胶凝材料及其制备方法，涉及复合材料领域。本申请中的锂渣基复合胶凝材料的制备方法包括如下步骤：S100、将锂渣与无机酸溶液混合后进行活化处理，得到活化物料，锂渣的组分包括铝硅酸盐；S200、将碱性物质和活化物料进行机械混合，得改性物料，改性物料的pH为7~10，然后将改性物料干燥，得改性粉体；S300、将改性粉体和辅料进行粉磨，得锂渣基复合胶凝材料。本申请的制备方法锂渣掺量高、成本较低，而且制得的锂渣基复合胶凝材料的抗压强度也较高。
