Casagrande Method for liquid limit
Portable apparatus used to evaluate the relationship between the percentage of humidity in a soil sample and the number of strokes needed to close a furrow made in the ground and therefore determine when a clayey soil changes from a plastic to a liquid state. The unit is made up of a removable brass cup which, by means of a cam device, falls onto a bakelite base (or hard rubber base).
TECHNICAL SPECIFICATIONS
The device consists of a removable cup which, by means of a lifting cam, falls repeatedly on a hard rubber base (or Bakelite). Available in two versions, with manual operation by crank (left or right side) or with motor operated at 120 drops / min of speed, ensuring better uniformity and precision
EQUIPMENT
Supplied complete with stroke counter, but without grooving tool, which must be ordered separately.
