Rheological behavior of cement pastes from MRI velocimetry
TL;DR: In this paper, it was shown from MRI measurements that in a flowing cement paste the thixotropic effects dominate over short time scales, while aging effects become significant over larger timescales.

Rheological behaviour of fresh cement pastes formulated from a Self Compacting Concrete (SCC)
TL;DR: In this paper, the authors proposed to study several cement pastes formulated from the original paste of a typical self-compacting concrete (SCC) mix, which will be used later to study the stability of coarse aggregates.

Modelling Thixotropic Behavior of Fresh Cement Pastes from MRI Measurements
TL;DR: In this paper, a simple thixotropic model based on MRI measurements was proposed to estimate the yield stress in a flowing cement paste, where the transition from the solid to the liquid regime is abrupt.
