新拌混凝土最基本的性质之一是其在振动状态下的结构粘度。以往在国际上曾提出过多种仪器来测定新拌混凝土在振动状态下的结构粘度,但使用起来都不太方便。(?)和黄蕴元在五十年代末已经解决了压模机参数、压模沉陷时间与混凝土拌合物结构粘度关系式的理论推导方法。如果压模机参数已经选定,循此方法推 One of the most basic properties of fresh concrete is its structural viscosity under vibration conditions. In the past, many instruments have been proposed in the world to measure the structural viscosity of fresh concrete under vibration, but they are not very convenient to use. (?) and Huang Yunyuan have solved the theoretical derivation methods for the relationship between the parameters of the molding press, the subsidence time of the stamper and the viscosity of the concrete mix in the late fifties. If the molding machine parameters have been selected, follow this method
