Description of ASTM-C311 2013ASTM C311 / C311M - 13Standard Test Methods for Sampling and Testing Fly Ash or Natural Pozzolans for Use in Portland-Cement ConcreteActive Standard ASTM C311 / C311M | Developed by Subcommittee: C09.24 Book of Standards Volume: 04.02 ASTM C311 / C311MSignificance and Use 4.1 These test methods are used to develop data for comparison with the requirements of Specification C618 or Specification C1697 . These test methods are based on standardized testing in the laboratory and are not intended to simulate job conditions. 4.1.1 Strength Activity Index The test for strength activity index is used to determine whether fly ash or natural pozzolan results in an acceptable level of strength development when used with hydraulic cement in concrete. Since the test is performed with mortar, the results may not provide a direct correlation of how the fly ash or natural pozzolan will contribute to strength in concrete. 4.1.2 Chemical Tests The chemical component determinations and the limits placed on each do not predict the performance of a fly ash or natural pozzolan with hydraulic cement in concrete, but collectively help describe composition and uniformity of the material. 1. Scope 1.1 These test methods cover procedures for sampling and testing fly ash and raw or calcined pozzolans for use in portland-cement concrete.
1.2 The procedures appear in the following order:
1.3 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.
Note 1 Sieve size is identified by its standard designation in Specification D1426 . The alternative designation
given in parentheses is for information only and does not represent a different standard sieve size.
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. 1.5 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes (excluding those in tables) shall not be considered as requirements of this standard.
