| 摘 要： | 通过预先在试验室内做出不过筛和过2 mm标准筛的级配碎石混合料的EDTA标准曲线,结合某新建高速铁路路基过渡段试验段的现场取样检测结果,对这2种检测方法进行相互对比验证,得出结论:在大面积、大方量的紧张施工中,采用混合料不过筛直接进行水泥剂量EDTA滴定,能够在施工现场快速测定水泥剂量,加大检测频率,是一种切实可行的检测手段。

| Abstract: | By making the standard curve of EDTA of macadam griddled by 2 mm standard griddle and the macadam without griddling,based on the sample result taken on site of a certain roadbed ramp of expressway,comparison is made between the two;the result shows that in intensive construction of large size and massive volume,the EDTA itration testing of the mixture without griddling can identify the dosage of cement quickly,which is a practical and actionable testing method. |
