1.1 This specification covers fly ash brick intended for use in masonry, which are made from fly ash, water, and suitable mineral aggregates with or without the inclusion of other materials, and without the use of portland cement. This specification covers units intended for use in masonry, in both structural and facing applications. 1.2 Units covered under this specification include a fly ash binder that undergoes hydraulic, pozzolanic, alkali-activated, or geopolymer reactions, or any combination thereof. These chemical reactions, in conjunction with the other materials in the units, provide the strength and durability necessary to meet the requirements of this specification. Note 1: This specification addresses properties of units
formed using fly ash, aggregates, and other allowed binders.
Although not required by this standard, users may request tests
that establish assembly performance such as unit-mortar bond and
fire resistance. As an alternative to tests, evidence of successful
use in similar applications could be provided to establish assembly
performance.
1.3 This specification references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use. |
