Abstract
The adsorption and desorption of water, the layer spacing of the montmorillonite with increasing water content and the heat of immersion with water have been measured for a Na-bentonite and two Ca-bentonites. The bentonite-water system is treated in terms of a micropore-filling process. Uptake of water occurs in discrete stages as the montmorillonite structure expands and the internal surface is calculated from these discrete stages of water adsorption.Keywords
