What nominal maximum sizes of aggregate are
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).

Aggregate size Concrete Construction Magazine
At a given water ratio, within the range employed in most structural concrete, smaller maximum sizes of aggregate will tend to produce higher concrete strengths than larger ones. 2. The larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower water-ratio than the smaller sizes. 3.
