Transcribed Image Text:Computing Relative Compaction from Sand Cone Data
Sand Cone Test Results:
●
Initial mass of sand cone apparatus = 5.912 kg
Final mass of sand cone apparatus = 2.378 kg
Mass of soil recovered from hole = 2.883 kg
Moisture content of soil from hole = 7%
Density of sand = 1300 kg/m³
Volume of cone below valve = 1.114 x 10-³ m³
Laboratory optimum moisture content 11.8% and
maximum dry unit weight is 19 kN/m³
Project requires RC ≥ 90% Standard Proctor
Compute dry unit weight and RC.
