Where can nominal maximum size aggregates be found?

Nominal maximum size aggregates are specified in ACI (American Concrete Institute) documents, and the reference that provides guidelines related to this topic is ACI 26.4.2.1. This section details the classifications and characteristics of aggregates used in concrete, including how the nominal maximum size is defined and how it affects concrete properties.

Understanding the concept of nominal maximum size aggregates is crucial as it influences the workability and strength of concrete mixtures. The nominal maximum size is the smallest sieve through which the entire amount of the aggregate material is permitted to pass, and it plays an important role in the overall performance and durability of concrete structures.

Other references, such as ASTM C33, which details standard specifications for concrete aggregates, are relevant but do not specifically define nominal maximum size within the same context provided by ACI. ACI 318, on the other hand, primarily focuses on structural design requirements, whereas Section 18.2.3 may cover related topics but does not specifically address nominal maximum size aggregates as clearly as ACI 26.4.2.1. Thus, the correct reference for this specific inquiry is indeed ACI 26.4.2.1.
