✦ Synopsis

The rheological behavior of kaolin and montmorillonite suspensions at low concentrations in water and polymer solutions has been investigated. An influence of the polymer concentration on the viscosity of suspension for the kaolin suspension in the presence of diethylenetriaminomethylated polyacrylamide and for the montmorillonite suspension in the presence of polyacrylic acid has been demonstrated. The dependence between the shear stress and the cross-sectional area of particles and the number of particles in a unit volume of the suspension has been shown. Mathematical equations for the number of aggregates in the unit volume of suspension and the number of initial particles in aggregate at the different polymer concentrations in mixture are proposed.

Because of their particular electric surface properties and crystal structure, most clay minerals possess a very high ion exchange capacity. Furthermore, the surface charge distribution is anisotropic: while faces of the laminar clay particles have a negative, pH-independent charge, edges may be pos

In this work we investigate some aspects of the rheological behavior of sodium montmorillonite (NaMt) suspensions in the pH range 3 to 9, of NaCl concentrations between 10(-3) and 10(-1) M, and of solid concentrations between 5 and 11% w/v. Three kinds of experiments were performed: steady-state vis
