cylindrical soil specimen of 50 mm diameter and 100 mm long is to be prepared from a dry soil. If the specimen required 15% water of its own dry weight and the volume of air voids are 20% from its total volume, calculate the weight of the soil and water required for sample preparation, known that the specific gravity of the soil is 2.69.

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.
