A sample of gray silty clay has a mass of 126 kg. Laboratory tests results give a moist density (ρ) of 2.05 g/cm3 , a specific gravity of solids (Gs) of 2.67, and a moisture content (w) of 14.7%. First determine all entries in the phase diagram. Then determine the void ratio (e), the porosity (n), the degree of saturation (S), the dry density (ρd), the dry unit weight (γd), and the moist unit weight (γ).

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.
