A sand cone test has been performed in a recently compacted fill. The test results were as follows: Initial weight of sand cone + sand = 6.14 kg Moisture Content Test: Final weight of sand cone + sand = 1.94 kg Mass of empty moisture can = 23.11 g Weight of sand to fill cone = 0.96 kg Mass of moist soil + can = 273.93 g Weight of soil from hole + bucket = 5.65 kg Mass of dry soil + can = 250.10 g Weight of bucket = 0.55 kg The sand used on the sand cone had a unit weight of 12.75 kN/m3 and the fill had a maximum dry unit weight of 19.04 kN/m3 and an optimum moisture content of 11.7 % a. Compute the volume of hole b. Compute the dry unit weight of soil. c. Compute the relative compaction.
A sand cone test has been performed in a recently compacted fill. The test results were as follows:
Initial weight of sand cone + sand = 6.14 kg Moisture Content Test:
Final weight of sand cone + sand = 1.94 kg Mass of empty moisture can = 23.11 g
Weight of sand to fill cone = 0.96 kg Mass of moist soil + can = 273.93 g
Weight of soil from hole + bucket = 5.65 kg Mass of dry soil + can = 250.10 g
Weight of bucket = 0.55 kg
The sand used on the sand cone had a unit weight of 12.75 kN/m3 and the fill had a maximum dry unit weight of 19.04 kN/m3 and an optimum moisture content of 11.7 %
a. Compute the volume of hole
b. Compute the dry unit weight of soil.
c. Compute the relative compaction.
