Bentonite 3, instead, was characterised by a markedly different value of SWI, 10 points higher than the other ones. Pertaining to LL, the test campaign to assess the liquid limits highlighted very high values, over 400% for all bentonites.

The test that is most useful to determine initial (freshly mixed) slurry properties is the Marsh Funnel (MF) test. The results of this test are related to bentonite content, the type of bentonite used and the degree of hydration. If there are impurities in the mix water that interfere with the hydration of the bentonite, this test will usually
