![]() ![]() Relieve the slurry sample slowly through the funnel’s screen.Hold the funnel upright and cover the bottom opening with the help of finger.Check Marsh funnel to be sure it is clean and that the outlet at the bottom of the funnel is immaculate throughout and free of obstructions.Take the bentonite sample at least two quarts (1.9 litres) in volume.Stopwatch or wristwatch with second handĮquipment-Marsh Cone Viscosity Test for BentoniteĪlso, Read: Bentonite Uses in Piling – Bentonite Slurry Preparation and Recyclingīentonite Marsh Cone Viscosity Test Procedure for Piling Work:.Equipment – Marsh Cone Viscosity Test for Bentonite: Bentonite Viscosity Tolerances for Pile construction is 30-40second. It is a widespread bentonite test for piling work. The test result gives us a tentative or partial indication of viscosity. For ease of construction work and quick results, we have carried out the Marsh Funnel Viscosity Test at the site. In this method, the obtained viscosity of bentonite slurry is not as accurate. Marsh Cone Viscosity test is also known as the Funnel viscosity test. Marsh Cone Viscosity – Bentonite Test for Piling: Marsh Cone Viscosity, pH Value, Sand Content and Specific gravity (Density) tests are considered routine bentonite tests for piling work. ![]() ![]() Following bentonite, tests are carried out at the site to maintain the stability of the borehole for piling operation. In this section, we discuss regarding Bentonite test for Piling, equipment and test procedure. ![]()
