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. Larger aggregate diameters reduce the quantity of cement and water needed because of its ...

Aggregates for Use In Concrete

Aggregate Size Effects: • As the maximum size aggregate increases, the amount of paste needed for a given slump decreases. • The maximum aggregate size used in a concrete mix is dictated by the size of the structural member and the spacing between reinforcing steel.

What nominal maximum sizes of aggregate are recommended?

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 ...
