The measurement scheme of rheological parameters of fresh cement-based materials and the processing method of measured data were given. The feasibility of different methods, i.e., using of the shear stress and shear strain rate displayed on rheometer, some approximate equations and solution to the Couette inverse problem was analyzed for calculating the rheological parameters of fresh cement-based materials. The analysis results show that the solution to the Couette inverse problem as a reasonable method can be used to obtain the rheological parameters of fresh cement-based materials. The corresponding calculation procedure was given. The influence of plug flow on the calculation of rheological parameters of fresh cement-based materials could be considered. The calculation of rheological parameters of fresh cement-based materials could be more accurate for the measured data in the absence of plug flow.
