· The typical coarse aggregate size ranges from 4.75 mm to 18 mm. Gravel or broken stone aggregates with rough and non-glassy texture are the best aggregates because they create a good bond with the cement paste. Aggregates need to be hard, strong, chemically inert, and non-porous.

Coarse aggregates are particulates that are greater than 9.5mm. The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete.

In concrete slabs, the nominal maximum size should not exceed three-fourths of the minimum clear spacing of reinforcing bars or one-third of the section depth (ACI 302.1R). The commentary R26.4.2.1(a)(5) of ACI 318-19 states that the size limitations on aggregates are provided to facilitate placement of concrete around the reinforcement without honeycombing due to blockage by closely …
