1.1 These test methods cover procedures for mixing and testing alkali-activated cementitious material (AACM).
1.2 These test methods and procedures appear in the following order:
| Sections |
Mechanical Mixing of Pastes and Mortars of Plastic Consistency | 4 – 10 |
Time of Setting of Pastes by Vicat Needle | 11 – 21 |
Compressive Strength | 22 – 35 |
1.3 These test methods reference notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the test methods.
1.4 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. If required results obtained from another standard are not reported in the same system of units as used by this standard, it is permitted to convert those results using the conversion factors found in the SI Quick Reference Guide.
1.5 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. (Warning—Fresh AACM mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.)
1.6 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.
