MXenes enhanced high-aluminum type iron tailing geopolymer and preparation method thereof
The invention discloses an MXenes enhanced high-aluminum type iron tailing geopolymer and a preparation method thereof. The geopolymer is prepared by pressing mineral powder, high-aluminum type iron tailings and MXenes under the excitation of an alkali activator. The geopolymer has the beneficial effects that the high-aluminum iron tailings are utilized, waste is turned into wealth, the alkali activator is utilized to excite the mineral powder, emission of carbon dioxide is reduced by reducing use of cement, the three-dimensional space structure of the geopolymer is changed by doping MXenes, various properties such as the electric shielding property of the high-aluminum iron tailings geopolymer are enhanced, and the geopolymer has the advantages of being high in strength, high in strength, good in stability and the like. The method has high added value, meets the requirement of low-carbon development, and has great significance in recycling iron tailings and reducing the emission of carbon dioxide in the building industry; the geopolymer is prepared in a compression molding manner, so that pores among particles can be reduced, the geopolymer is more compact, the pores among the particles are smaller, the pore structure of the geopolymer is improved, and the strength of the geopolymer is improved.
本申请公开了一种MXenes增强的高铝型铁尾矿地聚物及其制备方法，该地聚物由矿粉、高铝型铁尾矿、MXenes在碱激发剂激发下压制而成。本申请的有益效果如下：利用了高铝型铁尾矿，变废为宝，并且利用碱激发剂激发矿粉，通过减少水泥使用减少了二氧化碳的排放，并通过掺入MXenes改变了地聚物的三维空间结构，增强了高铝型铁尾矿地聚物的电屏蔽性等各项性能，具有较高的附加价值，并符合低碳发展的需求，对于铁尾矿资源化再利用以及减少建筑行业二氧化碳的排放具有重大意义；采用压制成型的方式来制备地聚物，可以减小颗粒之间的孔隙，使得地聚物更加致密，使得颗粒之间孔隙更小，改善了地聚物的孔隙结构，增大了地聚物的强度。
