bentonite samples for soda activation was found to be 40% in our preliminary activation studies on viscosity, swelling, and filtration loss. In soda activation, soda ash powder was added to the initially moisturized bentonite samples and kneaded till all the bentonite had reacted with soda. After soda addition and kneading, the activated

Alkali activation behaviour of un-calcined montmorillonite ...

The behaviour of these individual clay minerals suggests that the alkali activation of un-calcined 2:1 clay minerals is complex. Although alkali activation of montmorillonite can form a geopolymer, alkali activation of soils containing illite may lead to poor quality materials.

Acid Activated Clay

Acid-activated clays are produced almost exclusively from southern or nonswelling bentonites by treatment with various mineral acids. When used for their ability to decolorize or “bleach” color pigments from vegetable and petroleum oils, they are called bleaching clays or bleaching earths. Although sometimes confused with fuller’s earths, which are also sometimes called bleaching clays ...
