4) a) A wet sol in a barrel has mass of 100 kg. The barrel mass is 10 kg. Lab tests showed the water content of the soil is 5%. What is the dry mass of the soil? b) How many liters of water will be required to be added to increase the water content to 79% for optimum compaction? c) If the liquid imit is 60 and the plastic limit is 20; what will be the liquidity index if the moisture content is increased to 40%?

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…
