pose:
This test is performed to determine the magnitude and rate of volume
decrease that a laterally confined soil specimen undergoes when subjected
to different vertical pressures. From the measured data, the consolidation
curve (pressure-void ratio relationship) can be plotted. This data is useful in
determining the compression index, the recompression index and the
preconsolidation pressure (or maximum past pressure) of the soi. In
addition, the data obtained can also be used to determine the coefficient of
consolidation and the coefficient of secondary compression of the soil.
