THE RELATION BETWEEN COMPOSITION AND SWELLING …
THE RELATION BETWEEN COMPOSITION AND. SWELLING IN CLAYS*. margaret D. FOSTER. Geological Survey ABSTRACT. The' phenomenon of SWELLING is associated with the hydration of clay; however, all clays do not swell when hydrated. Steps in the mechanism of hydration and SWELLING of different types of clays as observed and intei'preted by several investigators and some theories proposed as to the cause of hydration and SWELLING are reviewed. The concept of clays as colloidal electrolytes that dissociate to a greater or less ex- tent when dispersed in water seems to explain most satisfactorily the significant rela- tion BETWEEN the degree of SWELLING on hydration and the COMPOSITION of the 'clay minerals.
