EDTA滴定法在石灰处理膨胀土中的应用研究

Study on Application of EDTA Titration in Lime Treated Expansive Soil

目前,在我国公路建设中石灰改良膨胀土的应用十分广泛。值得注意的是,为了保证改良土中灰剂量达到设计要求,需要对其进行检测,利用EDTA滴定法可以确定灰剂量。EDTA滴定法在实际工程中常用于快速测定石灰稳定土中石灰的剂量,还可以了解拌和的均匀性,整个检测过程快速、准确率高。本次研究重点分析EDTA滴定法在石灰处理膨胀土中的应用。

In current road construction in China,the application of lime-modified expansive soil is very extensive.It is worth noting that in order to ensure that the ash dosage in the improved soil meets the design requirements,it needs to be tested.The ash dosage can be determined by using the EDTA titration method,which is often used in the actual engineering to quickly determine the dosage of lime in the lime stabilized soil,and to understand the uniformity of the mixing.The entire inspection process is fast and accurate.This study focused on the application of EDTA titration in lime treated expansive soils.
