The objective of this work is to present the research progress and applications of fly ash-based geopolymer, and summarize the future research hotpots. Since 1998, scholars have made important contributions to the study of fly ash-based geopolymer, and a large number of research studies have been published. Therefore, a bibliometric analysis for the determination of the research status, trend, and history of fly ash-based geopolymer was conducted in the present study. A total of 4352 publications on fly ash-based geopolymer were collected between 1998 and 2022, with an increasing trend year by year. China and Australia are the largest contributors to the field, and the research institutions in each country cooperate closely. In addition, the most contributing research areas are MATERIALS SCIENCE, ENGINEERING, and CONSTRUCTION & BUILDING TECHNOLOGY. The keywords including fly ash, compressive strength, and mechanical property are the most frequently appearing words. On the whole, the development of fly ash-based geopolymer could be divided into three stages including the replacement of ordinary Portland cement, the development of multifunctional materials, and the reduction of environmental impact by the conversion of solid waste. This overview could provide an important guidance for the development of fly ash-based geopolymer.
这项工作的目的是介绍基于粉煤灰的地质聚合物的研究进展与应用，并总结未来的研究热点。自1998年以来，学者们对基于粉煤灰的地质聚合物的研究做出了重要贡献，发表了大量的研究成果。因此，本研究对基于粉煤灰的地质聚合物的研究现状、趋势和历史进行了文献计量分析。1998年至2022年期间共收集到4352篇关于基于粉煤灰的地质聚合物的出版物，且呈逐年增加的趋势。中国和澳大利亚是该领域最大的贡献者，两国的研究机构密切合作。此外，贡献最大的研究领域是材料科学、工程以及建筑与建造技术。包括粉煤灰、抗压强度和力学性能在内的关键词是出现频率最高的词汇。总体而言，基于粉煤灰的地质聚合物的发展可分为三个阶段，包括普通硅酸盐水泥的替代、多功能材料的开发以及通过固体废物转化减少环境影响。这一综述可为基于粉煤灰的地质聚合物的发展提供重要指导。
