Shrinkage Limit Set

Shrinkage Limit Set (AIM 045) Ref Std : IS 2720 (Part 6), ASTM D 427, BS 1377, AASHTO T 92

The Shrinkage Limit of a soil is defined as the moisture content after which any further reduction of moisture does not cause volume reduction. The shrinkage of clayey soil can be very significant. A fully saturated soil specimen is allowed to dry in free air and its volume is measured repeatedly by immersing in a mercury bath.  From the data obtained from this test, Shrinkage Limit, Shrinkage Ratio, Shrinkage Index and Volumetric Shrinkage can be calculated.The choice of puddle-clay material is often governed bythe results obtained from this test.
