Standard Test Methods for Bleeding of Concrete
|Publication Date:||10 July 1999|
|ICS Code (Concrete and concrete products):||91.100.30|
1.1 These test methods cover the determination of the relative quantity of mixing water that will bleed from a sample of freshly mixed concrete. Two test methods, that differ primarily in the degree of vibration to which the concrete sample is subjected, are included.
1.2 The two test methods are not expected to yield the same test results when samples of concrete from the same batch are tested by each method. When various concretes are to be compared, all the tests should be conducted using the same method, and if the batches are of similar unit weight, the sample masses should not differ by more than 2 lb (0.9 kg).
1.3 The values stated in inch-pound units are to be regarded as standard. The values in parentheses are provided for information purposes only.
1.4 This standard does not purport to address all of the safety problems, 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.
