盐溶液作用下地聚物固稳铬污染土强度及毒性浸出特性
Strength and toxic leaching characteristics of geosynthetically stabilized chromium-contaminated soils under the action of salt solutions
摘要
Abstract
Aiming at the problem of poor durability of traditional curing agent in solidified and stabilized contaminated soil,the strength characteristics and chloride ion leaching characteristics of Cr contaminated soil solidified by geopolymer curing agent under the erosion of NaCl solution were investigated through experiments.Compared with the cement curing agent,the results show that the geopolymer curing agent has better corrosion resistance;the unconfined compressive strength of geopolymer stabilized soil is always higher than that of cement stabilized soil,and the leaching concentration of total Cr and Cr(Ⅵ)is always lower than that of cement stabilized soil.The research conclusions can provide reference for the solidification stability of contaminated soil.关键词
