Sand Sand is a fine aggregate used in concrete and mortar to fill spaces between larger aggregate particles. It contributes to workability, strength, and a smooth finished surface.
The quality and grading of sand influence how easily concrete can be mixed, placed, and finished. Clean, properly graded sand helps create a dense concrete structure with consistent performance. Different construction applications may require specific types or sizes of sand depending on project specifications.
Frequently Asked Questions About Sand
What does sand do in concrete?
As fine aggregate it fills the spaces between larger particles, contributing to workability, density and a smooth finished surface.
Does the type of sand matter?
Yes. Clean, properly graded sand produces a dense, consistent mix. Silty or poorly graded sand weakens the concrete and hurts finishing.
Can any sand be used?
No. Construction sand must meet grading and cleanliness requirements. Beach or unwashed sand can introduce salts and fines that damage concrete.
