PHASE COMPOSITION OF FROZEN MONTMORILLONITE-WATER MIXTURES FROM HEAT CAPACITY MEASUREMENTS

EQUATIONS ARE WRITTEN GIVING THE BASIS OF A METHOD FOR DETERMINING THE UNFROZEN WATER CONTENT OF FROZEN, CLAY-WATER MIXTURES FROM HEAT CAPACITY MEASUREMENTS. THIS METHOD WAS EMPLOYED TO DETERMINE THE UNFROZEN WATER CONTENT OF FROZEN SODIUM-BENTONITE-WATER MIXTURES. THE DATA INDICATE THAT THE METHOD IS APPLICABLE AT TEMPERATURES BELOW ABOUT MINUS 5 DEGREES C. THE AMOUNT OF UNFROZEN WATER FOUND IN THE FROZEN CLAY-WATER MIXTURES AT MINUS 5 DEGREES TO MINUS 10 DEGREES C IS EQUIVANT TO AN INTERFACIAL SURFACE LAYER OF WATER OF FROM ONE TO TWO MOLECULAR DIAMETERS IN THICKNESS. MOST OF THIS WATER CAN BE ACCOMMODATED AND IS THOUGHT TO BE LOCATED IN INTERLAMMELLAR REGIONS. /AUTHOR/
