emphasized and appropriate test methods have been developed. Mineralogical and chemical composition affects the properties of bentonite. On the other hand, the measured physical characteristics are frequently used to interpret the mineralogical composition of bentonite. Two types of bentonite .
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 .

Test Procedure for SLURRY TESTING TxDOT Designation: Tex130E Effective Date: January 2009 1. SCOPE Part I of this test method covers sampling bentonite slurry. Part II determines the density of slurries used in slurry construction techniques, such as those used for barriers to control the horizontal movement of liquids.
The method adopted for testing is mud density balance; according to British standard: Density should be ≤ g/ml in fresh bentonite or recycled condition, the before concreting value should be ≤ g/ml. Local contractors usually supply ≤ g/ml ~≤ g/ml for fresh state and ≤ g/ml ~≤ g/ml for bentonite before concreting.
