摘要:
随着尾矿堆存量的不断增加，尾矿对人类安全、土壤及环境的危害也愈来愈严重，尾矿亟待处理。根据我国综合利用尾矿的现状，提出以碱激发地质聚合反应固化处理尾矿，着重介绍并论证了碱激发地质聚合反应固化尾矿的可行性，比较了碱激发反应和地质聚合反应在地质聚合反应理论的研究中的区别，指出地质聚合反应并不是碱激发反应的子集。同时，总结了表征碱激发地质聚合产物微观结构的技术，并展望了碱激发地质聚合反应固化尾矿的发展前景。
Abstract:With the continuous increase of tailings pile, tailings are becoming more and more harmful to human safety, soil and environment, so it is urgent to deal with tailings. Based on the present situation of comprehensive utilization of tailings in China, the paper proposed to deal with the tailings by alkali-activated geopolymerization. The feasibility of the solidification of tailings through alkali-excited geopolymerization was presented emphatically. Compared with the differences between alkaline-activated reaction and geopolymerization, the paper pointed out geopolymerization was not the subset of alkaline-activated reaction. Meanwhile, the techniques for characterizing the microstructure of alkali-activated geopolymer were summarized, and the development prospect of alkaline-activated geopolymerization was forecasted.
