Historical Standard: ASTM C1621/C1621M-09a Standard Test Method for Passing Ability of Self-Consolidating Concrete by J-Ring
SUPERSEDED (see Active link, below)
ASTM C1621 / C1621M
1. Scope
1.1 This test method covers determination of the passing ability of self-consolidating concrete by using the J-Ring in combination with a mold. The test method is limited to concrete with nominal maximum size of aggregate of up to 25 mm [1 in.].
1.2 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.
1.3 The text of this standard references notes that provide explanatory material. These notes (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. ( Warning Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)
