Motorized Liquid Limit

Description

Standard   : IS 2720 (PART-V) ASTM D 427, BS 1377

Model No. : PIT-046

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.

Motorised model with integral blowcounter,The Liquid Limit Device consistsof a hard rubber base(vulcanized rubber having hardness 86 IRHD)carrying a sliding carriage assemblyto 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.

Technical Specification
