Question

Sand is used in the cone is known to have a bulk density of 15.74 kN/m³

Wet weight=20.601 N

Dry weight =17.926 N

Weight of sand to fill test hole =16.053 N

a) Determine the in-place dry density of the tested soil (Ans. 17.57 kN/m³)

b) Determine the water content (Ans. 15%)

c) Compute the percentage of compaction of the tested soil if the laboratory moisture density curve indicates a dry density of 18.1 kN/m³ and an optimum moisture content of 13%. (Ans. 97.07%)
