Abstract

The effect of the exchangeable cations upon the gel structure of slurries obtained from two different types of bentonites found in Turkey and identified as swelling and non-swelling were determined. NaCl, KCl and CaCl2 of varying concentrations were added to these slurries and their effects on the rheological properties were determined. The results of this investigation highly suggests that the resulted swelling thixotropic gels depends mainly on the exchangeable cations added.
