ACI : Maximum Aggregate Size For Concrete Mix Design
In this post I shall discuss maximum aggregate size that can be used in design. Large maximum sizes of aggregates produce less voids than smaller sizes. Hence, concretes with the largersized aggregates require less mortar per unit volume of concrete, and of coarse it is the mortar which contains the most expensive ingredient, cement.
