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.

Question

a soil sample was determined to have a water
content of 8% and a degree of saturation of 42%.

volume of the voids, determine the following
A. void ratio
B. water content%
C. bulk specific gravity of the mass of the sample in
the altered state.
