Following are the results of a filed unit weight determination test on soil with the sand cone method: Calibrated dry density of Ottawa Sand = 1667kg/m³ Calibrated mass of Ottawa sand to fill the cone =0.177kg Mass of jar + cone + sand (before use) = 5.99kg Mass of jar + cone + sand (after use) = 2.81kg Mass of soil from hole = 3.331kg Moisture content of moist soil = 11.6% 38. Determine the dry unit weight of soil in the field. (kN/m³) с. 17.78 а. 18.56 b. 20.45 d. 16.25 39. If the maximum dry unit weight of the soil is, 17.54KN/m³, calculate the relative compaction. 92.67% b. 86.52% c. 88.97% d. 95.45% a.
