Abstract

The objective of this paper is to investigate the viscosity characteristics of fine-grained material (typically clay). A series of laboratory tests were conducted using MCR 102 rheometer to investigate the viscosity properties of the material under steady and dynamic conditions. The results indicate that the apparent viscosity at the same shear rate of Kaolinite is highly dependent on the shear rate and the W/S ratios, it decreases as the shear rate and the W/S ratios increase. In the considered frequency range, the complex viscosity of different W/S ratio sample have a nearly parallel linear trend in a log-log scale, and the complex viscosity sharply decreases with the frequency increasing.
