4.1 This test method is intended to provide the user with a procedure to determine slump of plastic hydraulic-cement concretes. 4.2 This test method is considered
applicable to plastic concrete having coarse aggregate up to
11/2 in. [37.5 mm] in size. If the
coarse aggregate is larger than 11/2 in.
[37.5 mm] in size, the test method is applicable when it is
performed on the fraction of concrete passing a
11/2-in. [37.5-mm] sieve, with the larger
aggregate being removed in accordance with the section titled
“Additional Procedure for Large Maximum Size Aggregate Concrete” in
Practice C172.
4.3 This test method is not considered applicable to non-plastic and non-cohesive concrete. 1.1 This test method covers
determination of slump of hydraulic-cement concrete, both in the
laboratory and in the field.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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. 1.3 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. 1.4 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.
