Title: Recomended Practice for Selecting Proportions
for Normal Weight Concrete (ACI 211.1-70)

Abstract:Describes, with examples, two methods for selecting and adjusting proportions for normal weight concrete. One method is based on an estimated weight of the concrete per unit volume; the other is based on calculations of the absolute volume occupied by the concrete ingredients. The procedures take into consideration the requirements for placeability, consistency, strength, and durability. Example calculations are shown for both methods, including adjustments based on the characteristics of the first trial batch.
