ASTM C55-99

Standard Specification for Concrete Brick

SCOPE
1.1 This specification covers concrete brick and similar solid units (see Note 3) intended for use in structural masonry or facing for buildings and other structures, and are made from portland cement, water, and suitable mineral aggregates with or without the inclusion of other materials.
1.2 The text of this standard 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 1—Concrete brick covered by this specification are made from lightweight or normal weight aggregates, or both.
Note 2—When particular features are desired, such as weight 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. Local suppliers should be consulted as to the availability of concrete brick having the desired features.
