From a compaction test the dry density of soil was found to be 1860kg/m3. when the water content was 15%. To determine the shear strength of soil in this condition a cylinder test specimen 100mm in diameter and 200mm long was prepared. Find the mass of oven dried soil and the water required for specimen. what would be the degree of saturation assuming specific gravity= 2.65

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.
