Abstract
Two bentonite samples from Gujarat have been investigated for elucidation
of their structures and constituents. Physico-chemical analyses
and infra-red, X-ray and thermal studies have been carried out, on
raw as well as acid treated clay samples, to understand the structural
changes on acid treatment of clays. Different degrees of swelling
shown by the clays have been explained in terms of their mineral content
and structural differences. Both high-swelling and low-swelling
bentonites have montmorillonites as the chief mineral constituent;
however, the latter has some amounts of quartz and kaolinite as
impurities. Low-swelling bentonite has considerable amount of substituted
aluminium atoms in the silica layers.
