Abstract: Suspensions of cement in water exhibit dispersion or coagulation at changing shear rate. After changing to higher or lower constant shear rate, the shear stress changes with time until steady state flow is obtained. Both the composition of the cement paste and the total content of water were found to affect the duration of the relaxation period of mortars. The relaxation period was most pronounced for mortars with low water content. A viscosity agent was found to shorten the relaxation period significantly.
