| description | The invention belongs to the technical field of building materials, and particularly relates to a preparation method of a red mud coal gangue accelerator. The preparation method solves the problems of high alkalinity, high production cost, serious environmental pollution, waste of mineral resources and the like of an alkali accelerator product prepared from bauxite at present, and combines the current situation that a large amount of red mud is stacked to generate alkaline substances to pollute the environment and a large amount of coal gangue is stacked to generate acidic substances to pollute the environment. The red mud and coal gangue based accelerator powder is obtained by mixing red mud and coal gangue, drying, crushing, activating, ball-milling, balling, firing and grinding. The preparation method has the advantages that the production cost of the accelerator is reduced, the waste of mineral resources is reduced, the resource utilization of solid wastes is increased, and the ecological environment is p |
