This invention discloses a method for thermal activation of coal gangue. Using coal gangue and an activating admixture as raw materials, the method involves sequential crushing, mixing and mechanical activation, homogenization, molding, drying, calcination and thermal activation, cooling, and grinding to prepare active powder. This invention uses coal gangue as the main raw material. By adding an activating admixture, the thermal activation temperature of the coal gangue is reduced to below 1000℃, significantly stimulating its activity. Simultaneously, combined with mechanical activation, unsaturated residual bonds are formed in the quartz minerals within the coal gangue, producing active silica, further stimulating the activity of the coal gangue and increasing its activation rate. The prepared active powder exhibits a pozzolanic activity of over 75%, achieving the goal of "waste treatment" and reducing costs. This active powder can be directly added as a mineral admixture during concrete preparation, showing promising application prospects.
