| Abstract: | Soft soil foundation treatment is an engineering field with high risk recognized by the engineering community. The large amount of Portland cement used in traditional soft soil stabilized not only consumes natural resources, but also has adverse effects on the environment. The use of environment friendly alkali-activated geopolymers to replace traditional Portland cement has attracted more and more attention. Based on the existing research results at home and abroad, the research progress from the historical development of alkali-activated geopolymer solidified soil, types of alkali-activated geopolymers, reaction mechanism of alkali-activated geopolymer, mechanical properties and various properties of alkali-activated geopolymer solidified soil were summarized and analyzed. The mechanical properties of soft soil treated by geopolymer were mainly discussed. At the same time, the impermeability, freeze-thaw resistance and corrosion resistance of different alkali-activated geopolymers in soft soil foundation reinforcement were also analyzed and studied. The application in soft soil foundation reinforcement is systematically reviewed and prospected, in order to guide and improve the application of alkali-activated geopolymers in soft soil foundation reinforcement, and realize the sustainable development of foundation reinforcement in China. |
