摘要
在室内和现场实验的基础上 ,分析比较了两种适合于中、小型工程的细骨料含水率简易测定法 :电阻率法及容量瓶法。总结了各自的优缺点和有效适用范围 ,并简述了按现场含水率实时调整混凝土配合比的具体步骤 ,并在实际工程中得到应用。
In this paper,two simple water-content measurement methods for fine aggregate,which are suitable for medium and small construction,were introduced.Their merits,drawbacks and respective area of application are also summarized.Several examples are given to illustrate the detailed operation procedures of measurement and adjustment.
