地质聚合物固化土研究现状及展望
State-of-the-art research and prospect of geopolymer solidified soil
摘要
Abstract
With fundamental research on geopolymer,the study of using geopolymer as solidification agent in the field of soil stabilization has received extensive attention.Geopolymer,as a new soil solidification agent,is a kind of green inorganic cementitious material formed by aluminosilicate-rich minerals as precursors under the action of alkali activators.It is equipped with the advantages of good mechanical properties,great durability,low carbon and environment friendly,etc.It can effectively overcome the disadvantages of high energy consumption,high pollution and poor durability of traditional soil solidification agents such as cement or lime,and is generally considered as an ideal substitute for traditional soil solidification agents.In order to clarify the solidification mechanism and reinforcement effect of geopolymers on soil,the research progress of geopolymer solidified soil in recent years is reviewed in this paper.Firstly,the reaction mechanism of geopolymer solidified soil is introduced;secondly,the influence of different factors on the mechanical properties such as unconfined compressive strength and shear strength is described in detail;thirdly,the durability of geopolymer solidified soil under freeze-thaw cycle,dry-wet cycle and chemical ion erosion is discussed;finally,the future study of geopolymer solidified soil technique is prospected.关键词
