Activated iron tailing powder, grouting material containing activated iron tailing powder and preparation method of grouting material
The invention belongs to the technical field of solid waste resource utilization. The invention provides activated iron tailing powder and a preparation method thereof. The preparation method comprises the following steps: sequentially grinding and drying iron tailing powder and a grinding aid to obtain a mixture; and the mixture and an active exciting agent are mixed and then excited, and activated iron tailing powder is obtained. The invention further provides a grouting material containing the activated iron tailing powder and a preparation method of the grouting material. The 28d compressive strength of the solid waste grouting material can reach 60 MPa or above, and the solid waste grouting material is good in fluidity, free of shrinkage and capable of achieving a micro-expansion effect. By activating the iron tailing powder, the utilization rate of the iron tailings is increased, the consumption of natural resources is reduced, and the method is more environment-friendly.
本发明属于固体废弃物资源化利用技术领域。本发明提供了一种活化铁尾矿粉及其制备方法。制备方法包含如下步骤：将铁尾矿粉和助磨剂顺次进行研磨、干燥，得到混合料；将混合料和活性激发剂混合后进行激发，得到活化铁尾矿粉。本发明还提供了一种含活化铁尾矿粉的灌浆料及其制备方法。本发明的固废灌浆料28d抗压强度可达60MPa以上，且流动性好，无收缩，具有微膨胀的效果。通过活化铁尾矿粉提高了铁尾矿的利用率，减少了天然资源的耗费，对环境更加友好。
