本文叙述用化学方法来确定混凝土在塑性阶段中的水和水泥含量。这个方法是应用氯离子滴定法测定水的含量,并用火焰光度计(钙量标记)测定水泥含量。如果这个方法可以用来估计混凝土的后期强度,并解释试验结果在多大程度上受到骨料的品种、骨料的潮湿状态、骨料吸水率、混凝土配合比、拌合时间和制样时间的影响,则本文对

This article describes the use of chemical methods to determine the water and cement content of concrete in the plastic stage. This method uses a chloride ion titration method to determine the water content and uses a flame photometer (calcium content marker) to determine the cement content. If this method can be used to estimate the late strength of concrete, and explain the extent to which the test results are affected by the type of aggregate, the wet state of the aggregate, the water absorption of the aggregate, the mix ratio of the concrete, the mixing time, and the sample preparation time , this article is
