The protocol was implemented to probe pastes modified with attapulgite clays, a highly thixotropic system, and was found to be effective in characterizing static yield stress and thixotropic rebuilding. Results provided support that the solid-liquid transition occurs beyond the critical stress measured through creep, thereby tying it to static yield stress. Flow curve derived from the tests illustrated a very shear thinning behaviour. Unstable results are observed near the yield stress, the value assigned being 3.6 Pa. LA-gellan gum fluid gels with Na + is the system selected to apply the method. The strains at which this transition occurred were compared with critical strains measured through low amplitude oscillatory shear. Creep-recovery-creep tests as a method to determine the yield stress are assessed. Through examining this bifurcation behavior we found that the transition of viscosity occurs at very low strains. Beyond a critical stress viscosity decreases and the material flows, exhibiting viscoelastic liquid-like behavior. When applied stress is sufficiently low viscosity increases and the material yields, exhibiting viscoelastic solid-like behavior. A viscosity bifurcation behavior was observed through applying a range of creep stresses. In this study, a creep recovery shear rheological protocol was applied to fresh cement pastes. 2016 Articles Use of creep recovery protocol to measure static yield stress and structural rebuilding of fresh cement pastes
