The #1 aggregate has a nominal size of 3.5 to 1.5 inches, while the #8 aggregate has a nominal size of 3/8 to .094 inch. #57 aggregate gets its name because it is a combination of the #5 and #7 aggregates, which means that its individual pieces …
Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve).
