Field Density, Specific Gravity & Relative Density

In-situ density of soil is an important parameter for soil engineers. This is needed for determination of bearing capacity of soils, stability analysis, natural slopes and for determining degree of compaction of fills.

Indian standards specify two different methods for in-situ density etermination ; core cutter method for fine grained soils free from aggregates and the sand replacement method for fine, medium and coarse grained soils having stones and pebbles etc.

The apparatus for sand replacement method as specified in ASTM D-1556 is also covered in our range of equipment.

Field Density Kit IS:2720 (Part XXIX)
