Aggregate Aggregate is the sand, gravel, crushed stone, or other mineral material mixed with cement and water to produce concrete. It makes up most of the concrete's total volume.
Aggregates provide bulk, stability, and strength while reducing shrinkage during curing. Their size, shape, cleanliness, and grading influence how the finished concrete performs. High-quality aggregates are essential for producing durable sidewalks, curbs, and driveways capable of withstanding years of service.
Frequently Asked Questions About Aggregate
What is aggregate in concrete?
The sand, gravel, crushed stone or other mineral material mixed with cement and water. It makes up most of the concrete's total volume.
What does aggregate contribute?
Bulk, stability and strength, while reducing shrinkage as the concrete cures.
Does aggregate quality matter?
Yes. Size, shape, cleanliness and grading all affect workability, strength and durability of the finished surface.
What is the difference between fine and coarse aggregate?
Fine aggregate is sand, which fills the spaces between particles. Coarse aggregate is gravel or crushed stone, which provides the structural skeleton of the mix.
