The invention provides an ardealite-based cementing material and a preparation method thereof. The ardealite-based cementing material comprises mixed powder and an admixture, and the mixed powder comprises, by mass, 40%-50% of ardealite, 44%-52% of solid waste residues and 6%-8% of an alkaline activator, totaling 100%; the additive is a mixture of sodium aluminate, lithium carbonate and layered bimetallic composite oxide, and the doping amount of the additive is 1.03%-4.05% of the mass of the mixed powder. The ardealite-based cementing material provided by the invention can solve the technical problems of long setting time and low early strength in the prior art.
本发明提供一种磷石膏基胶凝材料及其制备方法。所述磷石膏基胶凝材料包括混合粉体和外掺剂,所述混合粉体按照质量百分比计算,包括:磷石膏40%~50%,固废渣44%~52%,碱性激发剂6%~8%,总计100%;所述外掺剂为铝酸钠、碳酸锂、层状双金属复合氧化物三者的混合物,所述外掺剂的掺量为混合粉体质量的1.03%~4.05%。本发明的磷石膏基胶凝材料能解决现有凝结时间长、早期强度低的技术问题。
