Flow behavior of cementitious-like suspension with nano-Fe3O4 particles under external magnetic field

The flow behavior of cementitious-like (limestone powder) suspension containing nano-Fe 3 O 4 particles at constant shear rate of 10 s −1 , characterized by the evolution of apparent viscosity over time, is investigated under various magnetic fields. Results show that the limestone powder suspension at flow-state exhibits remarkable magneto-rheological responses, reflected by a significant increase in the apparent viscosity after applying an...
