Lithium slag-containing composite cementing material, preparation method and application thereof, and building material
The invention relates to the technical field of building materials, and discloses a lithium slag-containing composite cementing material, a preparation method and application thereof, and a building material. The method comprises the following steps: mixing and grinding the lithium slag and a component A; the mixing and grinding conditions are controlled, so that the Blaine specific surface area of the lithium slag-containing composite cementing material is 350-550m < 2 >/kg. By adopting the method provided by the invention, the lithium slag of which the activity does not reach the standard and harmful substances exceed the standard can be reasonably utilized, and when the composite cementing material prepared by the method is applied to concrete or cement, on the premise that the dosage of a water reducing agent or cement clinker is reduced, the utilization rate of the composite cementing material is improved. And a concrete or cement product with higher strength and good fluidity is obtained.
本发明涉及建筑材料技术领域，公开了一种含锂渣复合胶凝材料及其制备方法和应用、建筑材料。该方法包括：将锂渣与组分A进行混合粉磨；控制所述混合粉磨的条件，以使得含锂渣复合胶凝材料的勃氏比表面积为350‑550m2/kg。采用本发明提供的方法能够合理利用活性不达标且有害物质超标的锂渣，并且，将本发明方法制备得到的复合胶凝材料应用于混凝土或水泥中，能够在减少减水剂或水泥熟料用量的前提条件下，获得强度更高、流动性好的混凝土或水泥产品。
