HIGH-CONCENTRATION SOLID/WATER SLURRY AND PROCESS FOR PRODUCING THE SAME

摘要

A high-concentration solid/water slurry which has a high fluidity and excellent storability and transportation stability, and a process for producing the same. In the stress sweeping test for the determination of the dynamic viscoelasticity of this slurry, the maximum stress in a linear-elasticity region as determined at an oscillation frequency of 1 Hz is 0.3 to 10 Pa, and the strain of the slurry yielding the maximum stress in the linear-elasticity region is 2 % or higher. In the creep recovery test value determined in the linear elasticity region for the determination of the static viscoelasticity of the slurry, the elastic modulus of a Maxwell element analyzed by assuming a four-constant mechanical model based on Hookean elasticity and Newtonian viscosity is 8 to 70 Pa, and the elastic modulus of the Voigt element is 3 to 70 Pa.
