ASTM C311/C311M-22 PDF Download

The ASTM C311/C311M-22 standard is titled "Standard Test Methods for Sampling and Testing Fly Ash or Natural Pozzolans for Use in Portland-Cement Concrete." It covers procedures for sampling and testing fly ash and raw or calcined pozzolans for their suitability in portland-cement concrete.

The standard provides a specific order for the procedures, which includes various chemical analysis tests such as moisture content, loss on ignition, and determination of various oxides. It also includes physical tests such as density, fineness, drying shrinkage, soundness, air-entrainment, strength activity index, water requirement, and effectiveness in controlling alkali-silica reactions and sulfate resistance.

The standard specifies the use of different sections for each test procedure and also refers to other ASTM standards for sieving. It should be noted that the standard includes explanatory information in notes and footnotes, which are not considered as requirements of the standard except for those mentioned in tables.
