INTERPARTICLE ACTION AND RHEOLOGY OF DISPERSIVE CLAYS

The determination of the various interacting parameters in the phenomenon of clay soil dispersibility needs consideration of pore fluid chemistry, mineralogy and proportions of clay minerals, and resultant particle interaction. The need to develop an appreciation of soil dispersibility in view of the preceding has resulted in the examination of clay particle interaction with respect to the effects and influence of various salts, and in particular, the potential determining anions on the dispersive performance of certain clays. Various concentrations of NaC1, NaHCO3 and 15 meq/L NaOH were used in the preparaton of soils consisting of Kaolinite, ilite, montmorillonite, and mixtures of these clay minerals, with primary attention paid to kaolinite for the development of particle-interaction models for evaluation in terms of a flocculation-deflocculation status through a study of their rheological properties, light transmission, zeta potential, and adsorption-desorption phenomena.
