铝硅酸盐聚合物聚合机理与动力学研究进展

Recent Development on Geopolymerization Mechanism and Geopolymerization Kinetics of Geopolymers

近年来,铝硅酸盐聚合物因其原料来源广、工艺低碳绿色和性能独特等而引起学者的关注,并被寄予希望在更广泛的领域发挥作用。但铝硅酸盐聚合物的聚合行为易受原料反应活性的影响,进而引起其力学性能和耐久性等出现大幅波动。诸如上述相关问题均与铝硅酸盐聚合物的聚合机理、聚合反应动力学以及铝硅酸盐聚合物性能的影响因素与调控途径等直接相关,故本研究就此进行了综合评述,给出相关领域未来研究的发展方向,希望籍此推动低品质铝硅酸盐矿物或铝硅质工业废弃物利用,为中国早日实现“双碳”目标助力。

Geopolymers have attracted recent attention due to their wide source of raw materials,environmental protection,low-carbon technology and unique properties.However,the geopolymerization behavior of geopolymers is susceptible to the reaction reactivity of raw materials,leading to large fluctuations in the properties such as mechanical properties and durability.The issues mentioned above are directly related to the geopolymerization mechanism of geopolymers,geopolymerization kinetics,and influencing factors and regulation approach of the properties of geopolymers.Therefore,this review represented recent work and gave some future research aspects in this field to promote the utilization of low-quality aluminosilicate minerals or aluminosilicate industrial waste for the possible purpose of‘peak carbon dioxide emissions’and‘carbon neutrality’.
