SOIL
Shrinkage Limit
Pycnometer
Relevant Standards
BS 1377; ASTM D427; AASHTO T92
Description
The shrinkage limit in soil refers to the
upper limit of moisture content in soil after
which further reduction of moisture does
not cause any reduction in volume. In this
phenomenon the water content in fine
grained soil is reduced below the plastic
limit leading to shrinkage of the soil mass
till it achieves its shrinkage limit.
NOTE: Shrinkage limit is significant in
clays but less in case of silts and sands

Description
Pycnometer works on the principle
of Specific Gravity, which defines
the weight ratio of a given volume of
material in air with respect to an equal
volume of distilled water at the same
stated temperature. Powdered soil is
added to the pycnometer and weighed;
the pycnometer is filled with a liquid
of known density, in which the soil is
completely insoluble and weighed.
The weight of the displaced liquid can
be determined and hence the specific
gravity of the soil.
