Question

Bulking of sand is due to capillary action

Answer 1

Bulking of sand

This is the increase in volume of the sand.

This this happens when dry sand absorbs moisture.

When dry sand comes into contact with moisture, a thin film is formed around the particles which causes them to get apart from each other.

This is caused by capillarity.

Capillarity is the force that enables water to move up in soil.

Answer 2

Bulking of Sand

Explanation:

• Bulking of sand is dry sand retains moisture. At the point when dry sand comes into contact with moisture, a thin film is conformed to the particles which makes them get separated from one another. It is  caused about by capillarity
• The expansion in volume of sand because of moisture content is called bulking.
• The sands mass more than coarse sands.So, a simple method for deciding the building of sand is by finding the decrease in volume of the given sand when completely saturated
