45) What is the reason behind the decrease in dry density, especially in cohesionless soil with an increase in the moisture content?
- a) Degree of saturation
- b) Bulking of sand
- c) Capillary rise
- d) Water content

Answer: b) Bulking of sand
- The dry density decreases with an increase in moisture content in cohesionless soil under a low compaction effect. This is because of the bulking of sand in which the capillary tension resists the tendency of particles of soil to take a density state.
