稳定土中水泥或石灰剂量衰减问题的研究

Research on Content Attenuation in Lime or Cement Treated Base

利用乙二胺四乙酸 (EDTA)法可快速测定水泥或石灰稳定土中水泥或石灰剂量 ,通过室内和现场实验比较分析发现稳定土中的水泥或石灰剂量随时间衰减 ,会影响到现场测试结果 ,为此可建立EDTA消耗量和灰剂量回归公式 。

The paper focuses on the content attenuation in lime or cement treated base Using the method of EDTA, the lime or cement content can be gotten quickly in lime or cement treated base The data collected from lab and field study reveal that the content is declining with time, which will give false information if the date is checked in several days later The relation between EDTA and lime content is set up in this paper, in order to modify false date to its normal content It will be helpful for field compaction on subgrade
