Concrete aggregates are essential components of concrete, providing strength, volume, and durability. They come in two primary types:

Fine Aggregates: These smaller particles, typically sand, pass through a 4.75 mm sieve. Fine aggregates fill the gaps between larger aggregates, enhancing the workability and cohesiveness of the concrete mix.

Coarse Aggregates: These larger particles, such as gravel or crushed stone, are retained on a 4.75 mm sieve. Coarse aggregates contribute to the bulk and structural integrity of the concrete, ensuring it can withstand various loads and conditions.
