The sample used in the infiltration test had a diameter of 50 mm and height of 50 mm, and deionized water was injected at atmospheric pressure (0.1 MPa) from the bottom of the sample to observe the temporal change in the saturation of bentonite (Fig. 7). The dry density and water contents of the sample used in the tests were same as those Improving Local Bentonite Performance for Drilling,API specifications for acceptable drilling mud was the base for evaluating the local bentonite. The properties of the local mud can be improved economically by adding some cheep materials to the prepared mud to enhance its viscosity and filtration loss (such as CMC, Drispac polymer, and bentonite extenders).Bentonite Testing Lonquist Engineering ,The current API specifications for drilling grade bentonite are: Viscosity: Reading of 30 at 600 r/min.

For freshly mixed slurry, this test method may be used as an indicator of mix proportions. For intrench slurry or inborehole slurry, a certain value may be specified for maintaining trench or borehole stability.SoilBentonite Slurry Wall Specifications Especificaciones ,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
