The contact process is the same as the previous test except that only half of the bentonite was added at the start of the test. After agitating for half an hour, the oil was filtered, the second half of the bentonite added, and the test finished as usual. This process occupied one hour instead of half an hour.

Diaphragm Wall :: Trenching with Bentonite Fluid
The bentonite suspension used in bore holes is basically a clay of montmorillonite group having exchangeable sodium cations (Na+). The action of bentonite in stabilizing the sides of bore holes is primarily due to the thixotropic property of bentonite suspension.

Bentonite Properties Are Unique Bentonite is An Aluminum Silicate Clay That Is Used to Make Drilling Fluid in the Process of Mud Rotary Drilling of Water Wells, The water used to make drilling mud should always be checked using pH test strips (often available at a pharmacy) or a pH meter, Bentonite is a very special type of clay,
Bentonite Clay Waterproofing Membrane CLAYTITE W. R ...
CLAYTITE is a dual layer waterproofing consisting of HDPE (20 mil), sodium bentonite, and a protective layer consisting of a nonwoven polypropylene. The HDPE provides the first layer of waterproofing, while the bentonite's selfsealing capabilities ensure positive puncture protection under hydrostatic conditions.
Bentonite, Kaolin and Selected Clay Minerals (EHC 231, 2005)
1. SUMMARY Identity, physical and chemical properties, and analytical methods . Bentonite is a rock formed of highly colloidal and plastic clays composed mainly of montmorillonite, a clay mineral of the smectite group, and is produced by in situ devitrification of volcanic ash. In addition to montmorillonite, bentonite may contain feldspar, cristobalite, and crystalline quartz.
