Abstract:
The workability of blended cement-based materials depends strongly on the rheology of the
paste, which depends on various properties of its components. In this study the influence
of specific surface area and water-binder ratio on the yield stress and viscosity of blended
cement pastes were investigated. Both rheological parameters were seen to vary for the
evaluated design parameters. These rheological parameters were also compared with two
simple tests, mini slump and Marsh cone. It was learned that there is a strong relationship
between yield stress and surface area of pastes; however, the surface area did not influence
the viscosity of the pastes. It was also seen that the marsh cone was a better test, compared
to the mini slump cone test, to understand the rheology of blended cement based pastes.
