Density and porosity of bentonites SpringerLink

2012-4-10  The determination and/or calculation of the density of bentonite, however, is still under discussion. DeWit and Arends and Post investigated the density of smectites/bentonites as a function of the water content and expectedly proved the increase of the density upon dehydration. The density of the bentonites is closely related to the variable

Bentonite an overview ScienceDirect Topics

Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.
