SAND REPLACEMENT (INSITU-DENSITY) METHOD (IS 2720-PART-28-1974) Reaffirmed-2010 THEORY: The in-situ density is defined as the bulk density of soil measured at its actual depth. By conducting this test, it is possible to determine the field density of the soil. The moisture content is likely to vary from time and hence the field density also.
