1.1?This specification covers solid, dry-cast, concrete facing brick and other solid concrete masonry facing units intended for interior and exterior use in constructing structural and facing masonry components and are made from portland cement, water, and suitable mineral aggregates with or without the inclusion of other materials. Note 1:?Specification C55 addresses concrete building brick
used in non-facing, utilitarian applications (previously referred
to in earlier editions of Specification C55 as Grade Sfor general use where
moderate strength and resistance to frost action and moisture
penetration are required). This specification differs from
Specification C55 in that it
includes expanded consideration for properties of concrete units
used in facing applications and other exposures (previously
referred to in earlier editions of Specification C55 as Grade Nfor use as architectural
veneer and facing units in exterior walls and for use where high
strength and resistance to moisture penetration and severe frost
action are desired).
1.2?The text of 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. 1.3?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Note 2:?Concrete facing brick and other solid concrete masonry
facing units covered by this specification are made from
lightweight or normal weight aggregates, or both.
Note 3:?When particular features are desired, such as density
classification, high compressive strength, surface textures for
appearance or bond, finish, color, fire resistance, insulation,
acoustical properties, or other special features, such properties
should be specified separately by the purchaser. Suppliers should
be consulted as to the availability of concrete facing brick and
other concrete masonry facing units having the desired
features.
1.4?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. |
