ACI METHOD OF PROPORTIONING CONCRETE MIXES

Step 2. Choice of maximum size of aggregate. Large maximum sizes of aggregates produce less voids than smaller sizes. Hence, concretes with the larger-sized aggregates require less mortar per unit volume of concrete, and of coarse it is the mortar which contains the most expensive ingredient, cement. Thus the ACI method is based on the
