摘要/Abstract

摘要： 地质聚合物被认为是21世纪有可能大量取代水泥的绿色胶凝材料。本文综述了地质聚合物在软土加固方面的研究现状与进展:介绍了目前用于软土加固的地质聚合物前驱体和激发剂;归纳了地质聚合物加固软土的原理和机理;根据室内单元试验结果分析了地质聚合物固化土的变形和强度特性;讨论了地质聚合物固化土的渗透性和耐久性;总结了地质聚合物加固软土的环境影响和工程应用。与水泥固化土相比,在相同掺量下地质聚合物固化土的力学性能更好,且其CO₂排放量较低,因此地质聚合物可以替代水泥用于加固软土。将来可进一步研发性能更好的地质聚合物前驱体及绿色激发剂,并进一步研究不同类型地质聚合物固化土的宏微观力学特性。

Abstract: The geopolymer is considered to be a green cementitious material that likely to substantially replace cement in the 21st century. This paper summarized the research status and progress of geopolymer in the aspect of soft soil solidification. The current geopolymer precursor and activator for soft soil solidification were introduced. The principle and mechanism of solidifying soft clay by geopolymer were summarized. The deformation and strength characteristics of geopolymer solidified soils were analyzed according to the laboratory element test results. The permeability and durability performance of the geopolymer solidified soils were discussed. The environmental impact and engineering applications of solidifying soft clay by geopolymer were summarized. Compared with the cement solidified soil, the geopolymer solidified soil had better mechanical properties with the same admixture, and it had lower CO₂ emissions. Therefore, the polymer can be used to replace cement for solidifying soft soil. In the future, geopolymer precursors with better performance and green activators should be further developed, and the macro- and micro-mechanical properties of different types of geopolymer solidified soils should be further investigated.

Key words: geopolymer, solidifying soft clay, geopolymer solidified soil, precursor, activator, soft soil
