Aggregate Sizing Explained
Jan 15, 2016For example coarse aggregate has a standard grading requirement for each different size from #1 to #8. A #1 aggregate is a nominal size of 3 to 1 inches and a #8 aggregate is a nominal size of 3/8 to 0.094 inch. More specifically, a #57 aggregate is the combination of #5 and #7 aggregates ranging from 1 to 0.19 inch.

Aggregate Size In Concrete
Feb 03, 2022Coarse aggregate is any material whose particles are anywhere from 3/8 inches and 1.5 inches in width. This is the size of aggregate often used in road construction. Fine aggregate: Most fine aggregates consist of crushed stone or natural sand. Most of the present particles must be able to pass through a 3/8-inch sieve.

Aggregates
Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.
