Field Dry Density By Sand Replacement Method

Objective To determine the field density of soil by sand replacement method. Theory A hole of specified dimensions is excavated in the ground. The mass of the excavated soil is determined. The volume of the hole is determined by filling it with clean, uniform sand whose dry density (ρ d) is determined separately by calibration
