    WK42602

    1. Scope

    1.1 This test method covers determination of the compressive strength of alkali activated fly ash and raw or calcined natural pozzolan cement mortars, using 2-in. or [50-mm] cube specimens. 1.2 This test method covers the application of the test using either inch-pound or SI units. 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 nonconformance with the standard. 1.3 Values in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI-10, of measurements made in other units. 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. (WarningFresh alkali activated cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure)

    A new standard for alkali activated materials will: -Help products be accepted in the marketplace -Make it easier to ensure that consumers are provided with a quality product -Provide methodology to benchmark raw materials (e.g. fly ash) -Help to validate and compare results between different research groups
