EDTA滴定法测定掺水泥级配碎石中水泥剂量探讨

Discussion on the Determination of Cement Dosage by Railway Cement Graded Gravel EDTA Titration Method

文中通过研究试样数量、测定时间与EDTA消耗量的相关性、自来水、蒸馏水和无CO_(2)纯水等试验影响因素,对提高水泥剂量的检测精度具有一定的现实意义,有助于准确测定掺水泥级配碎石水泥剂量和控制现场施工质量,节约项目成本。

In this paper,by studying the correlation between the number of samples,the determination time and EDTA consumption,tap water,distilled water and CO_(2)free pure water and other test influencing factors,it has certain practical significance for improving the detection accuracy of cement dosage,which is conducive to accurately measuring the dosage of cement grade crushed stone cement,and is conducive to controlling the construction quality on site and saving cost.
