Composite mineral admixture as well as preparation method and application thereof
The invention discloses a composite mineral admixture as well as a preparation method and application thereof. The composite mineral admixture comprises the following components in parts by mass: 30-50 parts of mineral powder; 1 to 3 parts of gypsum powder; 30 to 50 parts of fly ash; 0 to 30 parts of steel slag; and 0.01 to 0.5 part of an exciting agent. The preparation method of the composite mineral admixture comprises the following steps: mixing the mineral powder, the gypsum powder and the exciting agent, grinding, adding the fly ash and the steel slag which are respectively ground to different particle size intervals, and uniformly mixing to obtain the composite mineral admixture. The composite mineral admixture can give full play to the ball bearing effect of the fly ash and the synergistic and complementary effect of multiple types of industrial waste residues, so that the low viscosity of a cement-based material and the high strength from the early stage to the later stage can be realized, and the composite mineral admixture is suitable for large-scale industrial application.
本发明公开了一种复合矿物掺合料及其制备方法和应用。本发明的复合矿物掺合料包括以下质量份的组分：矿粉：30份～50份；石膏粉末：1份～3份；粉煤灰：30份～50份；钢渣：0份～30份；激发剂：0.01份～0.5份。本发明的复合矿物掺合料的制备的方法包括以下步骤：将矿粉、石膏粉末和激发剂混合进行粉磨，再加入分别粉磨至不同粒度区间的粉煤灰和钢渣后混合均匀，即得复合矿物掺合料。本发明的复合矿物掺合料可以充分发挥粉煤灰的滚珠轴承效应以及多类别工业废渣的协同互补作用，从而可以实现水泥基材料的低粘度和在早期至后期的高强度，适合进行大规模工业应用。
