Description

Casagrande method in mechanical form is known as liquid limit method and has been in use for soil mechanics for a number of decades. The liquid limit data of soils is useful to correlate mechanical properties of soil, such as compressibility and lower shear strength. The Equipment is the water content at which soil passes from zero strength to an infinite strength, hence the true value of Liquid Limit cannot be determined.

Supplied complete with Casagrande Grooving Tool and Gauge Block (Type A of lS : 9259). Suitable for operation on 220 V, 50 Hz, single phase, AC supply. Hard rubber base, carrying housing sliding carriage and a cam to which a pulley is attached and which is belt driven by a 120 rpm synchronous motor.

Motorized model with integral blow counter, The Liquid Limit Device consists of a hard rubber base(vulcanized rubber having hardness 86 IRHD)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.

Accessories:

• Revolution counter fixed to the cam shaft having drop rate 2Rev/Sec: 1No.
• Casagrande type – A grooving tool: 1No.
• 10mm brass gauge block : 1No.
