Abstract: The paper deals with the behavior of fluid cement pastes, formulated from Self Consolidating Concretes (SCCs), and the experimental correlation of fundamental rheological properties, such as the yield stress and the viscosity, with measurements from field tests, such as the mini-cone slump flow test. As a matter of fact, several studies have shown that a correlation can be established between the yield stress and the cone flow diameter but hardly any parameter which could be correlated to the viscosity was found. In this study time flow measurements from mini-cone slump tests are considered and their suitability as indicators of the fluid cement paste viscosity investigated. An extension of the methodology to self consolidating concrete is also foreseen.
