(Test Method)Standard Test Method for Flow of Freshly Mixed Hydraulic Cement Concrete (Withdrawn 2014)
Standard Test Method for Flow of Freshly Mixed Hydraulic Cement Concrete (Withdrawn 2014)
SIGNIFICANCE AND USE
This test method permits a rapid assessment of the flow and consistency of freshly mixed concrete (see Note 1).
This test method also provides information on the change in flow and consistency, with time, of concrete containing superplasticizer admixtures.
This test method can be used to measure the uniformity characteristics of flow and consistency of freshly mixed concrete and its change with time.
Note 1—This test method may not be appropriate for use in evaluating gap-graded aggregate concrete.
SCOPE
1.1 This test method covers determination of the flow of a sample of freshly mixed concrete, either in the field or in the laboratory.
1.2 This test method is applicable to concrete having coarse aggregate up to 37.5 mm in size. If the coarse aggregate is larger than 37.5 mm in size, the test method is applicable when the fraction of concrete larger than 37.5 mm is removed in accordance with Practice C 172.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this 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. )
WITHDRAWN RATIONALE
This test method covers determination of the flow of a sample of freshly mixed concrete, either in the field or in the laboratory.
Formerly under the jurisdiction of Committee C09 on Concrete and Concrete Aggregates, this test method was withdrawn in April 2014. This standard is being withdrawn without replacement due to its limited use by industry.
