Scope of standard

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.
