Information technology has provided an opportunity to improve ways to transfer and store knowledge, yet a generally accepted framework involving more-automated exchanges and not been developed in the concrete industry. ACI Committee 235, Knowledge-Based Systems and Mathematical Modeling of Materials, sees the opportunity for the industry to establish a “virtual concrete community” that addresses the specific needs of the concrete industry and its customers, so that greater advances in understanding knowledge and improving practice can result.

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 con-sideration the requirements for placeability, consistency, strength, and durability. Example calculations are shown for both methods, including adjust-ments 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 in an appendix. This appendix uses the absolute volume method which is generally accepted and is more convenient for heavyweight concrete.

Curing is the maintaining of a satisfactory moisture content and termperature in concrete during its early stages so that desired properties may develop. Basic principles of curing are stated; commonly accepted methods, procedures, and materials are described. Requirements are given for curing pavements and other slabs on ground; for structures and buildings; and for mass concrete. For each of these categories, methods, materials, time, and temperature of curing are stated. Curing requirements for precast concrete products, shotcrete, preplaced aggregate concrete, refractory concrete, plaster, and other applications are given.
