Materials used to produce concrete must comply with which applicable standard?

The materials used to produce concrete must comply with ACI 318, which is the standard developed by the American Concrete Institute. This standard outlines the requirements for the design and construction of structural concrete. It specifies the minimum requirements for materials, design, construction, and enforcement to ensure that concrete structures are safe, durable, and perform as intended.

ACI 318 covers critical aspects such as the quality of concrete materials, including cement, aggregates, and admixtures, as well as their proportions and the structural aspects related to their use in concrete construction. Adhering to this standard ensures that structures can withstand various loads and environmental conditions.

The other options, while pertaining to different codes or guidelines, do not specifically address the material standards for concrete production in the same comprehensive manner as ACI 318 does.
