Consolidation test is un-dimentional test considered extremely
important in soil mechanics. Sample taken from adjacent areas of a
single site show differential settlement even when tested using same
techniques. Soil of similar strength may show varying consolidation.
Samples are very carefully prepared and vertical settlement of the
specimen in saturated or drained conditions carefully recorded when
known load is applied.
SPECIFICATION:
The standard outfit comprises of the following
items. Loading unit, maximum capacity 20kg/cm.sq. Having a
loading yoke connected to a lever arm with a counter balancing
adjustment and having a lever ratio of 1:1 the whole assembly being
