In order to establish a method of mesuring the flow properties of high-strength concrete, experiments have been conducted reffering to the Two-Point Method suggested by G. H. Tattersall. As a result, the following have been proven; 1) The tested apparatus is applicable to use on high-strength concerete with a widerange of consistency by means of using Tattersall's rotating impeller. 2) The value of relative plastic viscosityobtained by the Two-Point Method can be used for the viscosity equation of high-density suspension. 3) Relativeyield value have a close correlation to coarse aggregate volume concentration. Therefore, the plastic viscosityand yield values of concrete can be estimated based on those of mortar and concrete mixture.
