Abstract:
The rheological characteristics of montmorillonite suspension as a function of exchangeable sodium percentage (ESP), (when the complementary cation is either Ca2+ or Mg2+) and specific electrostatic charge density were studied in aqueous media at a clay concentration of 25 g kg-1, at pH 7 and temperature of 25oC. The differential viscosity and the extrapolated shear stress values of the various smectites (the electric charge density varied between 0.91 and 1.22 molc kg-1) suggest that the extent of particle-particle interaction in clay suspension decreases with increases in electrostatic charge density of smectites. -from Author
