Two ranges of yield stress, i.e., static and dynamic yield stress was measured. The static and dynamic yield stress should be used as the design input for grouting. The Flow Viz industrial rheometer can perform direct measurement of yield stress. The change of viscosity is abrupt just below and above the yield stress.
