ASTM C232/C232M-20a PDF Download

ASTM C232/C232M-20a is a standard test method that provides procedures for determining the bleeding of concrete. The bleeding of concrete refers to the relative quantity of mixing water that will separate from a freshly mixed sample of concrete. This test method can be used to evaluate the effect of different variables, such as composition, treatment, environment, or other factors, on the bleeding of concrete. It can also be used to assess the conformance of a product or treatment with requirements related to its impact on concrete bleeding.

The test involves using a specimen of concrete that has been consolidated by rodding. This simulates conditions in which the concrete is not subjected to intermittent vibration after placement. The procedure aims to determine the amount of mixing water that separates from the concrete sample during the test.

The standard includes various sections and references, such as the identification of sieve sizes, requirements for comparing different concretes, and explanatory notes and footnotes. It is important to note that the notes and footnotes provided in the standard are for explanatory purposes and should not be considered as requirements.
