Basics of Concrete - Aggregate
The term "aggregate" denotes a wide range of granular materials that may be used in the production of concrete, such as:
- Crushed Stone
- Natural Sand
- Manufactured Sand
These are basically divided into two categories: Fine Aggregate and Coarse Aggregate based upon their particle size.
Fine Aggregates consist of particles smaller than 1/4", usually sand or crushed stone
Coarse Aggregates are those with particle sizes larger than 1/4"
Aggregates make up 60% to 80% of the concrete volume
