Question
Sand cone equipment is used to determine an in-place unit weight (field density test) on a compacted earth fill. Ottowa sand is used in the cone and is known to have a bulk density of 1604 kg/m3. The laboratory moisture unit weight curve indicates a dry unit wt. of 19.20kN/m3 and an optimum moisture content of 13%.Soil sample dug from the test hole. Wet weight of soil sample = 2220 g. Dried weight of soil sample = 1930 g. Weight of sand to fill the test hole = 1936 g. c. Compute the percentage of compaction of the tested soil
