1、Designation:C163417Standard Specification forConcrete Facing Brick1This standard is issued under the fixed designation C1634;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.1.Scope*1.1 This specification covers solid,dry-cast,concrete facingbrick intended for interior and exterior use in constructingstructural and facing masonry components and are made
3、fromportland cement,water,and suitable mineral aggregates with orwithout the inclusion of other materials.NOTE1Specification C55 addresses concrete building brick used innon-facing,utilitarian applications(previously referred to in earliereditions of Specification C55 as Grade Sfor general use where
4、 moderatestrength and resistance to frost action and moisture penetration arerequired).This specification differs from Specification C55 in that itincludes expanded consideration for properties of concrete brick used infacing applications and other exposures(previously referred to in earliereditions
5、 of Specification C55 as Grade Nfor use as architectural veneerand facing units in exterior walls and for use where high strength andresistance to moisture penetration and severe frost action are desired).1.2 The text of this specification references notes andfootnotes which provide explanatory mate
6、rial.These notes andfootnotes(excluding those in tables and figures)shall not beconsidered as requirements of the standard.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
