The slurry rheology is required to be studied for evaluating the various hydraulic parameters such as optimum transport concentration design velocity pumping power specific power consumption etc 1 The rheology behavior of the slurry is essentially to be controlled in many industrial processesIdeally a slurry needs to be thin enough to pour and drain easily but it needs to thixotropic enough to form a gel after some time eg 1/2 hour so that it does not settle out Viscosity of glaze slurries is an important factor in their performance It seems obvious that ones of high viscosity will apply thicker to ware and vice versa

25 Slurry rheology The rheology of the slurries was characterized as a function of their water content using a combined motor and transducer CMT rheometer DHR 2 TA Instruments fitted with 40 mm diameter cross hatched top and bottom plates in a parallel plate configurationIn addition these polymers have a strong influence on the cement slurry rheology and are also often expected to play a role on cement particle suspension cement sheath homogeneity and to prevent settling The scope of this paper is to investigate the impact of several types of fluid loss polymers on cement slurry stability
