Relating Fresh Concrete Viscosity Measurements From Different Rheometers



Chiara F. Ferraris, Nicos Martys


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.
