Standard Specification for Expansive Components used in Hydraulic Cement Systems
1.1 This specification covers expansive components used with hydraulic cements that when combined and mixed with water, form an expansive component system that, after setting, increases in volume to a greater degree than the cement paste.
Note 1: Appendix X1 provides guidance for evaluating the performance of materials conforming to this specification for use in shrinkage-compensating concrete mixtures.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.3 The text of this standard refers to notes and footnotes and includes discussions of definitions that provide explanatory information. These shall not be considered as requirements of the standard, except for notes and footnotes in figures and tables.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
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.
