Abstract
The rheological properties of concrete need to be measured and predicted to enable the characterization of special concrete such as self-consolidating concrete (SCC). It was also shown by a round-robin held in 2000 [ , ] that different rheometers give a different values of viscosities for the same concrete. Therefore, the rheological properties of a concrete cannot be easily compared using different instruments. To remedy this situation, a new interpretation of the data was developed. It will be shown that all instruments tested could be compared by using a relative viscosity instead of the plastic viscosity. This will allow the indirect calibration of all rheometers.Citation
