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.

Broad coarse-aggregate gradation ranges are listed in Table 2 of ASTM C 33. These broad gradation bands are for use all across the country. Once a gradation is selected for a project, maintaining the gradation within tight ranges will achieve greater batch-to-batch consistency.

Coarse gradation. A gradation that, when plotted on the 0.45 power gradation graph, falls mostly below the 0.45 power maximum density line. The term generally applies to dense graded aggregate.
