Rheological characterization of a time dependent fresh cement paste

Abstract:

Combining equilibrium and non-equilibrium rheological tests, the yield stress and the plastic viscosity corresponding to the completely build-up structure of a fresh cement paste have been determined. This experimental method is proposed to characterize time-dependent fluids because the values of these parameters are not dependent on the particular structural state of the system and, consequently, are not affected by the particular way in which the rheological test has been designed. © 2009 Springer Science+Business Media, B.
