Question:

Sand cone equipment is used to perform a field density test on a compacted earth fill. Sand is used in the cone and is known to have a bulk density of 15.74 kN/m ³. The information available are the following:

Soil sample dug from the test hole, (wet weight) = 20.601 N

The dry weight of soil sample = 17.926 N

Weight of sand (sand cone) to fill test hole = 16.053 N

a) Determine the in-place dry density of the tested soil.

b) Determine the water content.

c) Compute the percentage of compaction of the tested soil if the laboratory moisture-density curve indicates a dry density of 18.10 kN/m ³ and an optimum moisture content of 13%.
