The
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. A counter to register the number of blows.
