dc.descriptionAbstract: Ionic concentration and water content profiles in frozen bentonite samples subject to a thermal gradient of 0.3°C cm^-1 but different temperature intervals were obtained in the temperature range from 0°C to -12°C in order to determine the extent to which thermal gradients influence the movement of ions in thin films of interfacial water. The moisture content distribution was found to remain virtually unchanged after times ranging from 20 to 54 days, indicating that ionic movement was not affected by mass flow of mobile water in thin films. The ionic distribution profiles were essentially as expected in the absence of a temperature gradient. These observations support the conclusion that thermal gradients have little influence on redistribution of ions in frozen earth materials.-
