摘要
Abstract
In this paper,soil solidification technology is used to study the influence of different proportions of cement,fly ash,lime and soil on solidifying effect of cadmium contaminated soil.The results show that cement,lime and fly ash can solidify the contaminated soil effectively.With the increase of curing agent added in soil,the compressive strength of the cured body becomes higher and the heavy metal leaching concentration becomes lower.The curing effects of the three curing agents are different.The experimental results indicate that the cement has greatest effect on soil solidification.When the cement,lime,fly ash are mixed together,the curing effect is better than using any one of them separately,the optimal curing ratio is 300％ of cement,30％ of fly ash and 10％ of lime.关键词
