    Significance and Use

    4.1 Common types of SCM include fly ash, slag cement, calcined clays, and silica fume. The introduction and widespread use of fly ash, slag cement, calcined clay, and silica fume have been characterized and supported by significant research and development programs, preconstruction testing, field testing and long term performance monitoring. As the technical and economic benefits of SCM have been recognized, and as sustainability and environmental awareness resulted in the need to develop new materials and new ways to use materials not previously utilized, new sources of potential SCM are being proposed for use in concrete as ASCM.

    4.2 If an ASCM does not yet have a significant record of performance in concrete, a comprehensive evaluation based on this Guide should be undertaken, and it should be recognized that this ASCM might be introduced for a specific project or into a limited marketplace to initially demonstrate its performance. The user should bear in mind the intended end use of the ASCM and use appropriate test methods to establish its suitability. An ASCM that demonstrates good performance through a comprehensive evaluation as outlined in this guide could then be considered to have access to broader markets and could be considered for inclusion in an ASTM standard for SCM. For this reason, the test program to demonstrate acceptable performance should include concrete mixtures with a range of characteristics specific to the ASCM’s intended use.

    4.3 In the absence of long-term durability or acceptable field performance, prospective users are advised to apply appropriate risk management and engineering practice in the use of an ASCM.

    1. Scope

    1.1 This Guide is intended to provide a technical approach to the evaluation of alternative supplementary cementitious materials such as pozzolans and hydraulic materials that fall outside the scope of Specifications C618, C989, and C1240. This Guide provides the initial steps for a comprehensive evaluation of an ASCM that provides due diligence for its specific intended uses in concrete; however, it does not evaluate conformance to all possible performance criteria for all types of concrete mixtures.

    1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.3 Performing the tests or meeting the test limits in this guide should not imply that the material tested meets the requirements of Specifications C618, C989, and C1240. These materials should not be represented as such and each specific source is to be evaluated separately.

    1.4 This guide does not purport to address all environmental and safety concerns, if any, associated with its use. It is the responsibility of the user of this guide to establish the appropriate environmental, health, and safety issues, and identify appropriate risk management procedures.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
