Abstract: Shear-induced particle migration is widely recognized to be a challenge in characterizing the shear rheological properties of fresh cement-based mortar systems. In this study, we aim to quantify particle migration by characterizing the de-structuration process during steady-state flow with the aid of a thixotropic model. The interaction of sand particles and the cement paste is explored through varying the sand volume and resting time.
