Aggregate Sizing Explained - Chaney Enterprises

Jan 15, 2016· For 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 ½ to 1 ½ 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.

Coarse aggregates are classified into two main groups: (i) single-size aggregate and (ii) graded aggregate. Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve.
