摘要: 粉煤灰制备成地质聚合物,不仅能够使固体废弃物得到资源化利用,而且还能够发挥地质聚合物在重金属离子吸附、防火保温、耐腐蚀以及低碳排放等领域的作用,从而实现资源的高效利用。主要总结了近年来粉煤灰基地质聚合物的研究及应用,并对当前存在的问题以及今后的发展趋势进行了总结和展望。Abstract: As the synthetic raw material of geopolymers, fly ash can not only make the solid waste be used as resources, but also give full play to the advantages of geopolymers in heavy metal ion adsorption, fire protection and heat preservation, corrosion resistance, low carbon emission and other fields, so as to realize the efficient utilization of resources. The research of fly ash based geopolymers and its application in recent years were summarized in this paper, and the current problems and future development trend were pointed out and prospected.
