Spherical Balls Settling Through a Quiescent Cement Paste Measured by X-ray Tomography: Influence of the Paste Thixotropy
Subhransu Dhar, Eduardo Machado-Charry, Robert Schennach +2
The settling of spherical balls in quiescent cement pastes of increasing age is studied. Metallic spheres with radii of 2, 2.5 and 3mm are dropped into the paste and allowed to set…

Discrepancies in dynamic yield stress measurements of cement pastes
Subhransu Dhar, Teresa Liberto, Catherine Barentin +2
The dynamic yield stress associated with the flow cessation of cement pastes is measured using a rheometer equipped with various shear geometries such as vane, helical, sandblasted…

Simple ions control the elasticity of calcite gels via interparticle forces
Teresa Liberto, Catherine Barentin, Jean Colombani +4
Suspensions of calcite in water are employed in many industrial fields such as paper filling, pharmaceutics, heritage conservation or building construction, where the rheological p…
