Standard Test Methods for Uncompacted Void Content of Fine Aggregate (as Influenced by Particle Shape, Surface Texture, and Grading) (Withdrawn 2015)

SCOPE
1.1 These test methods cover the determination of the loose uncompacted void content of a sample of fine aggregate. When measured on any aggregate of a known grading, void content provides an indication of that aggregate's angularity, sphericity, and surface texture compared with other fine aggregates tested in the same grading. When void content is measured on an as-received fine-aggregate grading, it can be an indicator of the effect of the fine aggregate on the workability of a mixture in which it may be used.
1.2 Three procedures are included for the measurement of void content. Two use graded fine aggregate (standard grading or as-received grading), and the other uses several individual size fractions for void content determinations:
1.2.1 Standard Graded Sample (Test Method A)—This test method uses a standard fine aggregate grading that is obtained by combining individual sieve fractions from a typical fine aggregate sieve analysis. See the section on Preparation of Test Samples for the grading.
1.2.2 Individual Size Fractions (Test Method B)—This test method uses each of three fine aggregate size fractions: (a) 2.36 mm (No. 8) to 1.18 mm (No. 16); (b) 1.18 mm (No. 16) to 600 m (No. 30); and (c) 600 m (No. 30) to 300 m (No. 50). For this test method, each size is tested separately.
1.2.3 As-Received Grading (Test Method C)—This test method uses that portion of the fine aggregate finer than a 4.75-mm (No. 4) sieve.
1.2.4 See the section on Significance and Use for guidance on the method to be used.
1.3 The values stated in SI units shall be regarded as 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.
WITHDRAWN RATIONALE
These test methods covered the determination of the loose uncompacted void content of a sample of fine aggregate.
Formerly under the jurisdiction of Committee C09 on Concrete and Concrete Aggregates, these test methods were withdrawn in January 2015 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
