hydration of the bentonite, this test will usually give the slurry specialist an indicator of that problem. While a 40 second MF slurry is typical of an initial bentonite slurry, variations from this value, both up and down, should be allowed to adjust the in-trench slurry as necessary. Water quality and bentonite quality have a major effect
Bentonite Clay is a unique its ability to produce an electrical charge when hydrated. Upon contact with fluid, its electrical components change, giving it the ability to absorb toxins. Bentonite is known for its ability to absorb and remove toxins, heavy metals, impurities, and chemicals.

Phase II involved four additional test procedures, one additional bentonite hydration condition, three additional concentrations of acetone (5%, 15%, 50%), and 100% methanol and xylene. About 64% of all indicator test data reported were generated during Phase II in an effort to establish a statistically viable data base for evaluation.

Jan 15, 2021 The YP/PV ratio specification (3 maximum) limits this amount of beneficiation. Hence, API bentonite, under many conditions, performs similarly to the nontreated bentonite. API OCMA Grade Bentonite - API OCMA Grade Bentonite is predominantly a calcium bentonite and as such, cannot meet specifications of either of the other two API-grade bentonites.
design test may be included in a specification with a one-per-project frequency, where an index test may have a frequency that is orders of magnitude more frequent. It is a normal compromise to balance the direct design utility of a test with a desire for a higher frequency.
