Following are the results of a field unit weight determination test on the same soil with the sand cone method:- • Calibrated dry density of Ottawa sand = 1667 kg/m • Calibrated mass of Ottawa sand to fill the cone = 0.117 kg • Mass of jar + cone + sand (before use) = 5.99 kg • Mass of jar + cone + sand (after use) = 2.81 kg • Mass of moist soil from hole = 3.331 kg • Moisture content of moist soil = 11.6% Determine a. Dry unit weight of compaction in the field
