2、icates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification covers two types of grout, fine and coarse grout, for
3、use in the construction of masonry structures. Eachtype (fine and coarse) is further classified as conventional grout (requiring mechanical consolidation by puddling or vibration whenplaced) and self-consolidating grout (not requiring mechanical consolidation when placed). Conventional grout is spec
4、ified by (1)proportions or (2) strength requirements. Self-consolidating grout is specified by strength requirements.1.2 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes(excluding those in tables and figures) shall not be cons
5、idered as requirements of this specification.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information only and are not considered standard.1.4 This international standard was de
