本文在分析混凝土工作性单点试验法的根本缺陷的基础上,详细介绍了两点试验法的原理和试验装置,指出采用两点试验可以了解拌合物在各种外界条件下的流变特性。文章还介绍了两点试验的影响因素以及控制混凝土质量的应用实例。
In this paper, based on the analysis of the fundamental defects of the single-point test method for concrete work, the principle and test device of the two-point test method are introduced in detail. It is pointed out that two-point test can be used to understand the rheology of the mixture under various external conditions. . The article also introduced the influencing factors of the two-point test and examples of applications for controlling concrete quality.
