Contamination of Groundwater by Grout Leachate

拟议的研究将解决各种机制， 水泥浆组分可以从稳定的土壤体中释放出来， 并测量这些成分在 沥水.这些浓度将由总有机 碳分析和电感耦合等离子体发射 分光光度法。毒性特征 浸出程序也将在最有前途的 为所研究的每种灌浆确定的配方。 浸泡和渗透试验中的渗滤液特性测试 对从原型灌浆球和急性灌浆球中挖掘出的样本进行了研究 并会进行毒性测试。

The proposed research will address the various mechanisms by which grout components could be released from the stabilized soil mass, and measure the resultant concentration of these components in the leachate. These concentrations will be determined by total organic carbon analysis and inductively-coupled plasma emission spectrophotometry, respectively. The toxicity characteristic leaching procedure will also be performed on the most promising of the formulations identified for each of the grouts investigated. Leachate characterization tests from soaking and permeation tests on samples excavated from the prototype grout bulbs and acute toxicity tests will also be conducted.
