Swelling Pressures of Dilute Na-Montmorillonite Pastes1
1958
Clays and clay minerals
Swelling pressures calculated from diffuse double-layer theory previously had been experimentally verified for Na-montmoriUonite at clay concentrations above 10 percent, but published data at clay concentrations less than 5 percent consistently showed osmotic pressures much lower than the maximum of about 40 cm water calculated from theory. Swelling pressures of Na-montmorillonite in 4-5 percent orientated suspensions were therefore measured in an specially constructed osmometer in various
