Yield stress and elastic modulus of suspensions of noncolloidal particles in yield stress fluids (2008, background): “This last property can also be measured through the slump test [Pashias et al. (1996); Roussel and Coussot (2005)], or through creep tests [Coussot et al. (2006)]: if a creep stress above the yield stress is imposed then the material flows steadily whereas for a creep stress below the yield stress…”
Effect of Coarse Particle Volume Fraction on the Yield Stress and Thixotropy of Cementitious Materials (2008, methodology): “On the other hand, as the strain 175 involved in this test is small, there should be no migration, nor extrapolation 176 problems, in the slump test used by Ancey and Jorrot [33], as long as the yield 177 stress is high enough to avoid spreading of the material and the correlation 178 between measur”
