通过郑州市西绕城公路改建工程六标段水泥稳定碎石基层水泥剂量的检测,对EDTA滴定法测定水泥剂量的操作方法提出一些看法,用不同取样方法对水泥稳定碎石料进行滴定分析,确定出比较符合现场实际的水泥剂量取样滴定方法。以便及时、准确地确定出水泥稳定碎石混合料的水泥剂量,从而保证水泥稳定层的施工质量,指导施工。 Through the detection of the cement dosage of the cement stabilized macadam base in Sixth Segment of Zhengzhou City West Ring Road Reconstruction Project, some opinions on the operation method of EDTA titration for the determination of cement dosage were put forward. Titration of cement stabilized aggregates by different sampling methods was carried out, Determine more in line with the actual site of the sampling method of cement titration. In order to timely and accurately determine the cement stabilized aggregate mixture of cement dosage, so as to ensure the construction quality of cement stabilized layer, guiding the construction.
