Liquid Limit Device

Liquid Limit Device, Casagrande Method, Motorised and Manual Models (AIM 040, AIM 041) Ref Std : IS 2720 (Part 5), IS 9259, BS 1377

The liquid limit defined as the moisture content at which the soil passes from plastic state to liquid state, is very helpful for the classification of the potential properties of the soil material. The liquid limit gives a measure of the shearing resistance which a soil has, when mixed with water. The liquid limit of soil can be determined byCasagrande Method or Cone Penetrometer Method.
Casagrande Method
Ref. Standards: IS:2720 (Part 5), IS:9259, BS 1377 Mechanical method known as the Casagrande Method has been a standardised test in Soil Mechanics for  many years.
• High quality of design ensures consistency of results
• Satisfies International Standards
• Motorised model with integral blow counter is also available
The Liquid Limit Device consists of a hard rubber base carrying a sliding carriage assembly to which a brass cup is hinged. The cup is raised and allowed to fall through a height of 1 cm on to the hard rubber base, with the help of a lead screw provided at the back of the sliding carriage. Supplied complete with Casagrande Grooving Tool and Gauge Block (Type A of IS : 9259).

Suitable for operation on 220 V, 50 Hz, single phase, AC supply.

Measurement of moisture content and dry density.
