ASTM C232/C232M-21 PDF Download

The ASTM C232/C232M-21 standard outlines a procedure to determine the amount of mixing water that will bleed from a freshly mixed concrete sample. The scope of the standard specifies that the relative quantity of bleed water is measured.

The standard emphasizes the importance of comparing batches of similar unit weight when analyzing and comparing various concretes. It states that the sample masses should not differ by more than 1 kg (2 lb) to ensure accurate and meaningful comparisons.

Additionally, the standard includes a note that provides information about sieve sizes, highlighting that the standard designation in Specification E11 should be used to identify sieve sizes, while any alternative designation given in parentheses is purely for informational purposes and does not represent a different standard sieve size.

The standard also notes that the text contains additional explanatory material in the form of notes and footnotes. It clarifies that these notes and footnotes (excluding those in tables and figures) should not be treated as requirements of the standard, but rather as supplementary information.
