The sand cone test determines the dry density of soil samples through a process involving both field work and laboratory work. In the field, a soil sample is collected and poured into a sand cone apparatus to displace a known volume of sand. The displaced sand is then weighed to calculate the dry density. In the lab, the soil sample is dried and weighed to determine moisture content, …
