This publication describes methods for selecting and adjusting proportions for normal weight concrete. The procedures take into consideration the requirements for placeability, consistency, strength, and durability. Example calculations are shown, including adjustments based on the characteristics of the first trial batch. The proportioning of heavyweight concrete for such purposes as radiation shielding and bridge counterweight structures is described.
