碱渣固化锌污染土的工程性质试验研究

Engineering properties of alkaline solidified/stabilized zinc contaminated soils

采用无侧限抗压试验、淋滤试验等方法,对碱渣固化锌污染土的工程性质、淋滤特性进行了研究。通过试验研究得到以下结论:无侧限抗压强度随着锌离子浓度的增加呈下降趋势;无侧限抗压强度随着碱渣掺量的增加先增大后减小,在碱渣掺量为30%时得到最大值。

The engineering properties and leachability of solidified/stabilized zinc-contaminated soil based on alkaline residue have been investigated with the method of Unconfined Compressive Strength（UCS）Test and Leaching Test.And the conclusions can be drawn as following：The Unconfined Compressive Strength（UCS）decreases with the increase of zinc concentrations.With the increase of alkaline residue content,the UCS increases initially then decrease,and reach the peak when the alkaline residue content is 30%.
