The coarse aggregate grading can be assessed petrographically from core specimens and finely ground slices, while the fine aggregate grading is best assessed in thin section. The main types of grading for coarse aggregates are continuous, single-size, and gap-graded.

Aggregate Sizing Explained The term "aggregates" as used in the construction industry is a broad category of coarse and fine particulate material including sand, gravel, crushed stone, slag, recycled concrete, and geosynthetic aggregates and are actually the most mined materials in the world.

Typically, coarse aggregate sizes are larger than 4.75 mm (5 mm in British code), while fine aggregates form the portion below 4.75 mm. A maximum size up to 40 mm is used for coarse aggregate in most structural applications, while for mass concreting purposes such as dams, sizes up to 150 mm may be used.

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.

Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch sieve.
