Question

Data for field density by sand cone method:

Weight of bottle + cone + sand before going to the field = 8990.5 g

Weight of soil excavated from hole = 7550 g

Weight of bottle + cone + sand after use = 2931 g

Weight of sand required to fill the cone, Wc = 1578 g

Dry unit weight of sand = 1.533 g/cm3

Moisture content = 6%

1- Calculate dry unit weight of compaction in the field.
