LIQUID LIMIT CASAGRANDE METHOD

Category:

Used to evaluate the relationship between the moisture percentage
of a soil sample and the number of blows required to close a groove
made into the soil and therefore to determine when a clay soil
changes from a plastic to a liquid state.
The unit comprises a removable brass cup which through a cam
device drops on a bakelite base (or hard rubber base). Supplied
complete with drops counter, but without grooving tool which has
to be ordered separately.
The instrument is available in two versions:
– hand operated through crank (left or right side)
– motor operated at 120 drops/min speed, ensuring better
uniformity and accuracy
