Thixotropic behavior of cement paste under large amplitude oscillatory shear
Appl. Rheol. 27:5 (2017) 53914 (9 pages)
►
Cement-based materials exhibit highly complex rheological properties, in particular yielding and thixotropy. These two properties
can be characterized by considering rebuilding under a constant stress (creep) after shear at high rate. The rebuilding
kinetics can be considered through the time evolution of the viscoelastic properties. However at the beginning of the rebuilding
process the oscillatory behavior may be non-linear since the microstructure is destroyed by the shear flow. In the present investigation
the rebuilding kinetics of cement pastes under oscillatory stress is considered through the transition from large amplitude
oscillatory shear (LAOS) regime to small amplitude oscillatory shear (SAOS) regime. Three different cement paste mixes
are considered: plain cement, nano-clay blended cement paste and cellulose ether blended cement paste. These three mixes
are selected in order to deal with qualitatively different rheological properties.
