Unfired red-mud-based geopolymer and preparation method thereof
The invention discloses an unfired red-mud-based geopolymer and a preparation method thereof. Red mud and coal gangue are sequentially subjected to mechanical ball-milling activation and alkali-activated activation treatment so as to obtain the unfired red-mud-based geopolymer. According to the method, the activity of the red mud and the coal gangue is improved through synergism of a mechanical force excitation and alkali excitation cooperation mode, the geopolymer with high reaction activity is obtained, the problem that the activity of red mud and coal gangue raw materials is low in the geopolymer production process is solved, and meanwhile, energy consumption generated in the process of improving the reaction activity through calcination of the red mud and the coal gangue is reduced.
本发明公开了一种免烧赤泥基地聚合物及其制备方法。将赤泥与煤矸石依次经过机械球磨活化和碱激发活化处理，即得免烧赤泥基地聚合物。该方法利用机械力激发协同碱激发方式提升赤泥和煤矸石的活性，获得高反应活性地聚合物，解决了地聚合物生产过程中赤泥及煤矸石原料活性低问题，同时减少了赤泥煤矸石采用煅烧提高反应活性过程中产生的能耗。
