Summary

The effect of a single cation on the gelation and time-dependent rheological stability of clay slurry was determined using cation exchange resins. Two different comparison points were chosen to evaluate the differences between ions: equal viscosity and equal rate of viscosity change. The rheological characterization of clay slurries with salt additions showed that for equal cation concentration at the same viscosity, the effect of the different anions could not be differentiated. It was also shown that at equal anion concentrations at the same rate of change of viscosity, the effect of the different cations could be more differentiated. However, comparing the salt-doped clays with the sodium clay, it was shown that bom anions and cations increased we elastic and viscous moduli as well as the yield stress of the day suspensions.
