1、Designation: C476 10Standard Specification forGrout for Masonry1This standard is issued under the fixed designation C476; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates
2、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 Department of Defense.1. Scope*1.1 This specification covers two types of grout, fine andcoarse grout, for use in the co
3、nstruction of masonry structures.Each type (fine and coarse) is further classified as conventionalgrout (requiring mechanical consolidation by puddling orvibration when placed) and self-consolidating grout (not re-quiring mechanical consolidation when placed). Conventionalgrout is specified by (1) p
4、roportions or (2) strength require-ments. Self-consolidating grout is specified by strength re-quirements.1.2 The text of this specification references notes andfootnotes that provide explanatory material. These notes andfootnotes (excluding those in tables and figures) shall not beconsidered as req
5、uirements of this specification.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.2. Referenced Documents2.1 ASTM Standards:2C5 Specifi
