Abstract: As a new aluminosilicate inorganic geopolymer cementitious material, the special hydration reaction mechanism and hydration products have made more research and application in the field of immobilized/stabilized toxic heavy metal ions. In this paper, the mechanism, products, structure and properties of geopolymer reaction, the mechanism of immobilization/stabilization of toxic heavy metal ions, and the factors that affect the effect of geopolymer immobilization/stabilization of toxic heavy metal ions were reviewed.We also provided the theoretical basis and ideas for the research on making use of the low utilization efficiency industrial waste (Bayer process red mud) to synthesize geopolymer and its properties of immobilizing/stabilizing toxic heavy metal ions. Finally, the shortcomings and the future prospects of the research on utilizing geopolymer to immobilize/stabilize the toxic heavy metal ions are pointed out.
