The purpose of this study is to establish evaluation method of workability for plastering materials. In this paper, we attempted to develop an inclined blades rotational rheometer in order to evaluate workability of plastering materials. And we investigated the appropriate method to evaluate workability on this apparatus, such as measurement method and analysis method.
As a result, it was found that the measurement conditions and the sample characteristics were major factors to influence the results of measurements. And inclined blades rotational rheometer could evaluate the viscosity and consistency of samples.
