Standard Test Method for Bleeding of Concrete

SIGNIFICANCE AND USE
4.1 This test method provides procedures to be used for determining the effect of variables of composition, treatment, environment, or other factors in the bleeding of concrete. It is also permitted to be used to determine the conformance of a product or treatment with a requirement relating to its effect on bleeding of concrete.  
4.2 A specimen consolidated by rodding and tested without further disturbance simulates conditions in which the concrete is not subjected to intermittent vibration after placement.
SCOPE
1.1 This test method covers the determination of the relative quantity of mixing water that will bleed from a sample of freshly mixed concrete.  
1.2 When various concretes are to be compared, if the batches are of similar unit weight, the sample masses shall not differ by more than 1 kg [2 lb].  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Some values have only SI units because the inch-pound equivalents are not used in practice.Note 1—Sieve size is identified by its standard designation in Specification E11. the alternative designation given in parentheses is for information only and does not represent a different standard sieve size.  
1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure).2
