“Permeability of soil” and various factors affecting permeability.
i

Factors affecting “Compaction”.

Different methods of soil exploration.

Importance of ‘Study of soil ‘in engineering.

Undisturbed sample of soil has a volume of 100 cm³ and weighs 190 g. On oven drying for 24 hours, the weight reduces to 160 g. If the specific gravity of grains is 2.68, determine the water content, void ratio and degree of saturation.
