Description and Specification for Lab Tenders
Liquid Limit Device.
Liquid Limit Testing determines the water content at which soil changes
from a liquid to a plastic state.The liquid limit data of soils is
useful to compare mechanical properties of soil, such as lower shear
strength and compressibility. Liquid limit is the water content at
which soil passes from zero strength to an infinite strength. Liquid
limit is that water content limit at which a part of soil, cut by a
groove of standard dimensions flows together for a distance of 1.25cm
under an impact of 25 blows in a standard liquid limit apparatus. It
consists of 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. It is provided with one
Casagrande grooving tool, one grooving tool and a height gauge
block. Now a days this motorized(120 rpm) device facilitated with
counter is available.
