Abstract
The physico-chemical properties of three bentonites from Jammu and Kashmir
and one from Gujarat have been studied. Chemical analyses and bee, dta and X-ray
measurements were carried out. In addition, the characteristic properties of bentonites
like swelling and thixotropy were also critically examined.
The study revealed that the clay from Gujarat was essentially smectitic in character
belonging to a mixed sodium and calcium base type. Of the three clays from Jammu
and Kashmir, one was fairly pure montmorillonite, the other two having a large proportion
of impurities mostly siliceous in nature. All the three bentonites belonged to
the calcium-magnesium base type.
