一、流变常数的测定 Ish—shalom和Greenberg提出的回转粘度计是测定一般物质粘度较普遍采用的装置,目前仍广泛用于新拌水泥净浆的粘度测定。然而用它测定时,在转筒等速连续回转的情况下,随着时间的变化,转矩不断减小,不能获得定值。为此,作者研究改进了L’He
I. Determination of rheological constants The rotary viscometer proposed by Ish-Shalom and Greenberg is a commonly used device for determining the viscosity of general substances and is still widely used for the determination of the viscosity of fresh cement paste. However, when it is measured with it, the torque decreases continuously with the change of time when the drum is continuously rotated at a constant speed, and a fixed value cannot be obtained. For this reason, the author studied and improved L’He
