Solid waste-based composite lithium slag ultra-fine admixture as well as preparation method and application thereof
The invention discloses a solid waste-based composite lithium slag ultrafine admixture and a preparation method and application thereof, the solid waste-based composite lithium slag ultrafine admixture comprises the following raw materials: lithium slag, steel slag, coal gangue and fly ash, and also comprises a liquid activator composed of water, polymeric polyol, triisopropanolamine, triethanolamine, calcium lignosulphonate, molasses and calcium formate. The admixture is used for replacing 8-12% of cement raw materials in cement mortar, and the 28-day strength of the cement mortar is improved by 4-6 MPa while the cement consumption is reduced.
本发明公开了一种固废基复合锂渣超微细掺合料及其制备方法与应用，其原料包括锂渣、钢渣、煤矸石和粉煤灰，还包括由水、聚合多元醇、三异丙醇胺、三乙醇胺、木钙、糖蜜和甲酸钙构成的液体激发剂。本发明的掺合料用于替代水泥砂浆中8％～12％的水泥原料，在减少水泥用量的同时，使水泥砂浆28天强度提高4～6MPa。
