NEED AND SCOPE OF EXPERIMEN

FIELD DENSITY TEST BY SAND REPLACEMENT METHOD

FIELD DENSITY TEST BY SAND REPLACEMENT METHOD

OBJECTIVE
Determine the in situ density of natural or compacted soils using sand pouring cylinders.NEED AND SCOPE
The in situ density of natural soil is needed for the determination of bearing capacity of soils, for the purpose of stability analysis of slopes, for the determination of pressures on underlying strata for the calculation of settlement and the design of underground structures.
