INDUSTRIAL APPLICATIONS OF BENTONITE by
bentonite was applied as e~rly as 1848 by Knight to a highly plastic clay material occurring near Fort Benton, Wyoming (Grim, 1953, p. containing small amounts of alkali and alkaline+arth metals. Structurally, montmorillonite is made of two basic building blocks, the aluminum octa processing, and in each case the raw materials consist

REACTION OF BENTONITE IN LOW ALKALI CEMENT
bentonite barriers. The hyperalkaline (pH~13) leachates from the cement are expected to cause alteration of the bentonite. Low alkali cements produce lower pH (around 1011) leachates and it is expected that this will slow bentonite reaction (or even stop it altogether) over the timespan of relevance to repository safety.

Why is NonTreated Sodium Bentonite
Bentonite is a type of clay formed by chemical decomposition or decay of volcanic ash, tuff and lavas which are rich in terms of aluminum and magnesium. The most important feature is the montmorillonite group clay minerals, which are basically bentonite which can swell. Main rocky of bentonite is the volcanic ash and tuff.
