Liquid Limit Device (With Counter) For Testing Lab Description and Specifications for Lab Tenders
Liquid Limit Device (With Counter).
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. Liquid limit 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. For determination purpose liquid limit is
that water content at which a part of soil, cut by a groove of standard
dimensions, will flow together for a distance of 1.25cm under an impact
of 25 blows in a standard liquid limit apparatus. The soil at the water
content has some strength which is about 0.17N/cm. sq. (17gms/sq.cm.) .
At this water content soil just passes from liquid state to plastic
state. It consists on a brass cup held on an adjustable bracket. The cup
can be adjusted for a fall of 1 cm and can be raised an dropped on a
rubber base of standard hardness by cam action. Complete with one
Casagrande grooving tool, one ASTM grooving tool and a height gauge
block.
