Ultrafine carbonate type tailing-based active material, preparation method thereof and application of ultrafine carbonate type tailing-based active material as cement material
The invention discloses an ultrafine carbonate type tailing-based active material, a preparation method thereof and an application of the ultrafine carbonate type tailing-based active material as a cement material, and the preparation method comprises the following steps: drying and crushing ultrafine carbonate type tailings, and calcining at 750-850 DEG C to obtain the ultrafine carbonate type tailing-based active material; the active material has good hydration activity, can replace part of high-performance sulphoaluminate cement for application, greatly reduce the use cost of the sulphoaluminate cement, and is simple in preparation process, low in cost, low in energy consumption and beneficial to industrial production.
本发明公开了一种超细碳酸盐型尾矿基活性材料及其制备方法和作为水泥材料的应用，将超细碳酸盐型尾矿经过干燥和破碎后，置于750℃～850℃下进行煅烧处理，即得超细碳酸盐型尾矿基活性材料；该活性材料具有较好的水化活性，可以替换部分高性能硫铝酸盐水泥应用，大大降低了硫铝酸盐水泥的使用成本，且其制备工艺简单，成本低，能耗低，有利于工业化生产。
