There is a noticeable decrease in viscosity after 156 seconds, when the spindle reverses direction and works its way back up through previously tested clay. The spindle “drills” down into the sample from 0 to 156 seconds. Data from this test is shown in Figure 1. Rheocalc software controlled the Brookfield DV2T Viscometer.


This may be a big advantage when testing materials whose structure breaks down and take significant time to rebuild. The Helipath tests “fresh” material as it rotates the T-bar spindle moving downward into the sample. A Helipath stand was used with the small T-F spindle because of the high viscosity and “pasty” nature of the sample. The mixture was tested within a 600 mL, low form, Griffin beaker at room temperature, about 23☌. The 10% by weight concentration of clay in solution was created with distilled water and tested.
