1. Scope
1. Scope 1.1 This practice covers procedures for fabricating test specimens in the laboratory or field with a representative sample of fresh self-consolidating concrete (SCC). This practice is applicable to SCC with a nominal maximum aggregate size up to 25 mm [1 in.] and a slump flow of 500 mm [20 in.] or greater. Note 1: When the slump flow is less then 500 mm [20 in.] follow the fabrication procedures described in the standard for which the test specimen is required. 1.2 The values stated in either SI units or inch-pound units shall 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 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 exposed skin and tissue upon prolonged exposure.2) 1.4 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.
Self-consolidating concrete is being used routinely in the concrete construction industry.There are currently no standard practices for making and curing self-consolidating concrete test specimens and the existing practices for conventional concrete are not applicable.
