AGGREGATES

SEE ALSO SAND

Concrete Aggregates Shape: Generally rounded in shape. The reason: Rounded  particles improve workability and reduce internal friction during Mixing, Pumping and Placement. They also help ensure uniform strength in concrete Texture: Smoother Types: River rock and crushed stone with controlled surface

Road Base Aggregates Shape: Typically angular and irregular Reason: Angular particles interlock better under compaction, providing higher stability and strength for load-bearing purposes in base and sub-base layers Texture: Often rough, which provides stability and prevents displacement.
