Swelling Pressure of Montmorillonite Layers versus H-O-H Bending Frequency of the Interlayer Water
Bending Frequency Hydration Infrared Spectroscopy Interlayer Force Interlayer Water Montmorillonite Swelling Pressure
2011/12/27
The in-depth perturbation of vicinal water by the surfaces of montmorillonite layers was investigated by relating the swelling pressure, Π, of the montmorillonite layers to the H-O-H bending frequency...
The Effect of Unequal Ionic Size on the Swelling Pressure in Clays
Clay Swelling pressure Unequal ion size
2011/12/31
In this paper, we use the unequal radius modified Gouy-Chapman theory to evaluate the effect of the ionic size of the electrolyte on the swelling pressures (II) in different clay systems immersed in e...
Effects of Octahedral-Iron Reduction and Swelling Pressure on Interlayer Distances in Na-Nontronite
Interlayer distance Iron Nontronite Reduction Swelling pressure X-ray powder diffraction
2012/1/5
A new type of environmental chamber for X-ray diffraction was designed that could sustain elevated, internal pressures of nitrogen or any other gas under oxygen-free conditions and that allowed the po...
Swelling Pressure Calculated from Mineralogical Properties of a Jurassic Opalinum Shale, Switzerland
Gouy double layer theory Mineralogical composition Shale Soil mechanics Surface area Surface charge Swelling pressure
2012/2/2
Nineteen drill core samples of lower Dogger opalinum shale from wells drilled in connection with a tunnel project near Brugg, northern Switzerland, were investigated. The shale is a well known swellin...
Direct Measurement of the Relation Between Swelling Pressure and Interlayer Distance in Li-Vermiculite
Double-layer theory Interlayer distance Swelling pressure Vermiculite X-ray diffraction
2012/2/1
To test the double-layer theory of swelling as applied to layer silicates, the interlayer separation, ? in a Li-saturated vermiculite from Grouse Creek, Utah, was measured as a function of the swellin...
