Quick Indicator Tests To Characterize Bentonite Type

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.
