The volume increase of fine aggregate due to moisture content is known as bulking. Fine sand bulks more than coarse sand—extremely fine sand, particularly the manufactured fine aggregate bulks, as much as about 40%.

Bulking of Sand
Bulking of sand refers to the increase in volume of sand when it is saturated with water. This phenomenon is important to consider in construction and engineering projects where accurate measurements and calculations are necessary.
Explanation
More in Fine Sand:
- Fine sand has smaller particles compared to coarse or medium sand.
- The smaller particles in fine sand have a larger surface area, allowing them to hold more water.
- When fine sand is saturated with water, the water fills the spaces between the particles, causing them to separate and increase in volume.
- This increase in volume due to water content is more pronounced in fine sand, leading to greater bulking compared to coarse or medium sand.
Implications in Construction:
- When estimating the amount of sand needed for a project, it is crucial to account for bulking to ensure accurate calculations.
- Failure to consider bulking can result in shortages of sand, leading to delays and additional costs in construction projects.
In conclusion, bulking of sand is more significant in fine sand due to the smaller particle size and larger surface area, allowing for greater water retention and volume increase when saturated. It is essential to account for bulking in construction projects to avoid inaccuracies in material calculations.
