Aggregate Sizing Explained - Chaney Enterprises
Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve. This is then broken down into four types of grading Zones 1 through Zone 4 with Zone 4 being the most fine. Coarse aggregate can be described as uncrushed, crushed, or partially crushed gravel or stone.

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.
