ASTM C233/C233M-18 PDF Download

ASTM C233/C233M-18 is a standard test method used to evaluate materials that are proposed for use as air-entraining admixtures in concrete. The purpose of this test is to generate data for comparison with the requirements outlined in Specification C260/C260M. It is important to note that the tests conducted in this method are not meant to replicate real-world job conditions, but rather to facilitate highly standardized testing in a laboratory setting.

The standard includes various provisions and references important notes and footnotes. These notes and footnotes, excluding those in tables and figures, do not hold the status of requirements but rather provide explanatory information. Additionally, the standard makes use of sieve sizes, which are identified by their standard designations in Specification E11. Alternative designations given in parentheses do not indicate different standard sieve sizes and are provided for informational purposes only.
