setting time and rheological properties, is ambiguous [4, 7].
The results of the research  indicate a reduction of the yield stress and plastic viscosity with the increase in limestone content in cement, while the results of studies  indicate the opposite relationships. Authors of works [3, 10] showed a decrease in the yield stress and an increase of plastic viscosity with an increase in the limestone content. The results of tests are usually only related to the chemical and physical properties

to the decrease of zeta potential. The yield stress is a key parameter in production, determining the force required to fill a product into its container or to flow. The stress at the viscosity maximum, is a measure for the yield stress. The yield stress is 0.07 pa which it shows that small amount of force is required to flow.
(a) Viscosity vs. stress, (b) Viscosity vs. shear rate
Cross rheological model shear thinning model gives a good agreement with measured data. γ̇ is the shear
