Q: Pick up the correct statement from the following.
  • A. Adding 5% to 6% moisture content by weight, increases the volume of dry sand from 18% to 38%
  • B. The bulking of fine sand is more than that of coarse sand
  • C. If the percentage content of moisture exceeds 10%, increase in bulk of sand starts decreasing
  • D. All options are correct
Correct Answer: Option D - The bulking of sand is the phenomenon of increases in sand volume due to the increase of moisture content when moisture content is 5 to 6% of weight then volume 30 to 40% increased for the fine grain sand surface area is more than coarse grained sand so fine grain sand more bulking than coarse dry sand.
D. The bulking of sand is the phenomenon of increases in sand volume due to the increase of moisture content when moisture content is 5 to 6% of weight then volume 30 to 40% increased for the fine grain sand surface area is more than coarse grained sand so fine grain sand more bulking than coarse dry sand.

Explanations:

The bulking of sand is the phenomenon of increases in sand volume due to the increase of moisture content when moisture content is 5 to 6% of weight then volume 30 to 40% increased for the fine grain sand surface area is more than coarse grained sand so fine grain sand more bulking than coarse dry sand.
