Coarse aggregates are granular materials with particle sizes larger than 4.75 mm (0.1875 inches), typically retained on a 4.75 mm sieve during particle size analysis. These aggregates play a crucial role in providing structural strength and stability to construction materials such as concrete and asphalt.

The dividing line between fine and coarse aggregate is the 3/8-inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100 (see Table 1). The FM for fine aggregate should fall ...
