ACI 221R-96 (R2001) PDF Download

ACI 221R-96 (R2001) is a standard. It provides guidance on the use of various aggregates, such as sand, gravel, crushed stone, and air-cooled blast-furnace slag, in the production of concrete. The standard focuses on evaluating the properties of these aggregates and how they affect the properties of the concrete.

The standard outlines methods for determining aggregate properties and provides guidance on their preparation, handling, and selection. It emphasizes the importance of understanding the influence of different aggregate properties on the final properties of the concrete. By evaluating these properties, engineers and concrete producers can make informed decisions about the type and proportions of aggregates to use in concrete mixtures.
