1.1 This specification covers solid, dry-cast, concrete building brick intended for interior and exterior use in constructing structural masonry, and are made from portland cement, water, and suitable mineral aggregates with or without the inclusion of other materials. Note 1: Specification C1634 addresses concrete facing brick
used in facing applications and other exposures (previously
referred to in earlier editions of this standard as Grade N—for 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). This specification differs from
C1634 in that it addresses
properties for concrete building brick used in non-facing,
utilitarian applications (previously referred to in earlier
editions of this specification as Grade S—for general use where
moderate strength and resistance to frost action and moisture
penetration are required).
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 the standard. The values given in parentheses are for information only. Note 2: Concrete building brick 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 building brick
having the desired features.
1.4 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. |
