AS PER IS: 2720 (Part XXIX) - 1966.
This is used for determination of in situ dry density of natural or compacted fine grained soil, free from aggregates.
A cylindrical cutter is used to extract a sample of the soil with the help of a dolly and rammer.
From the weight, density and the moisture, and dry density of the soil is ready calculated.
