A laboratory test container holds a volume of 1/30 ft3 (0.000943 m3). The container is carefully filled with a dry sand, 1.36 kg, to determine a value for the minimum density. The specific gravity of the soil solids is 2.70. Determine the dry density (kg/m3), the dry unit weight (in both kN/m3 and pcf ), and the void ratio.

Soil Compaction Test

Soil compaction is the major area of geotechnical engineering. Soil is composed of multiple pores present on its surface, while the soil is mainly composed of gravel, sand, rocks, etc. The arrangement of these rocks and gravels is such that they build up voids (spaces) between them, which allows spaces for the roots of the plants and crops to spread and absorb the required amount of nutrients. Soil compaction is a major problem primarily caused by human activities, micro-organisms, and other multiple factors.
