Aggregate

Definition: granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a cementing medium to produce either concrete or mortar.- ACI Concrete Terminology


Aggregates are the major constituent (ingredient) in concrete, making up 60% to 70% of the volume of concrete. Aggregates influence the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete. Particle size divides aggregates into two categories: fine and coarse. Most fine aggregates are sand and contain particles smaller than 3/8 in. (10 mm). Coarse aggregates may be either gravel or crushed materials, with particles larger than about 1/4 in. (6 mm).
