Casagrande apparatus

Casagrande apparatus is used as an alternative to the cone penetrometer, to determine the moisture content at which clay soils pass from a plastic to a liquid state (the liquid limit).

This method evaluates 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, a bakelite base, a cam device which drops the cup on the base, and a drop counter.
