Determine the dry unit weight of compaction in the field. (ANS: 14.97kn/m3) PLS ANSWER NUMBER 2 WITH COMPLETE SOLUTION 2. What is the relative compaction in the field if the maximum dry unit weight in the laboratory is 15.93
As part of a quality controlprogram, the field inspection
engineer conducted a sand cone test to determine the field density. The
following data were recorded using the sand cone method.
• Calibrated dry density of Ottawa sand = 1667 ??/?3
• Mass of Ottawa sand to fill the cone = 0.117 kg
• Mass of jar + cone + sand (before use) = 6.1 kg
• Mass of jar + cone + sand (after use) = 2.83 kg
• Mass of moist soil from hole = 3.35 kg
• Moisture content of moist soil = 16.1%
a. Determine the dry unit weight of compaction in the field. (ANS: 14.97kn/m3)
PLS ANSWER NUMBER 2 WITH COMPLETE SOLUTION
2. What is the relative compaction in the field if the maximum dry unit weight in the laboratory is 15.93 ??/?3?
