Sand-cone equipment is used to determine an in-place unit weight (field density test) on a compacted earth fill. The sand used in the cone is known to have a bulk density of 15.73 kN/m3 Wet weight of soil sample dug from test hole = 2100 g Dried weight of soil sample = 1827 g Weight of sand (sand core) to fill the test hole = 1636 g a) Compute the water content. b) Compute the in-place dry unit weight of tested soil. c) Compute the percentage of compaction of the tested soil if the laboratory moisture-unti weight curve indicates a dry unit weight of 18.09 kN/m3 and a optimum moisture content of 13%.
