Analysis of Rheological Models of Selected Cement Slurries [PDF]
Acta Montanistica Slovaca, 2004 Cement slurries become more and more widely applicable in reinforcing and strengthening the rock mass. The processes taking place in fresh cement slurries were presented and their complex character analysed. The equations describing rheological models, e.

Investigation into the transportation and melting of thick ice slurries in pipes [PDF]
, 2008 This paper presents the results of experiments and modelling carried out on ice slurries flowing in uninsulated steel pipes with a nominal diameter of 50 mm. The slurries used were formed from 4.75% NaCl aqueous solution and had ice mass fractions in the

The anomalous pressure drop behaviour of ice slurries flowing through constrictions [PDF]
, 2008 The effective ‘viscosity’ for ice slurry containing more than say 30 to 40% ice fraction is many orders of magnitude higher than that for water. However, this work suggests that such slurries, when flowing through constrictions, can incur lower pressure ...

Micro-slurry jet for surface processing of dental ceramics
Biosurface and Biotribology, 2019 A micro-slurry jet (MSJ) was used for removing microscopic cracks and microstructural defects on surfaces of dental ceramics, in which the MSJ functioned as a wet blasting machine using mixed alumina particles and water to spray workpiece surfaces by a ...

Optical Characterization of Industrial Slurries
KONA Powder and Particle Journal, 2015 In this work we focus on the characterization of micro- and nano-powders typically adopted for chemical mechanical polishing, extensively used whenever the global and local planarization of surfaces is required as in nanoelectronic fabs.
