(Specification)Standard Specification for Concrete Facing Brick
Standard Specification for Concrete Facing Brick
ABSTRACT
This specification covers solid, dry-cast, concrete facing brick 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. Concrete facing bricks shall be grouped into density classifications as either lightweight, medium weight, or normal weight. Specimens shall be sampled, tested, and conform accordingly to the specified physical requirements (oven-dry density, maximum water absorption, and minimum net area compressive strength) suitable for their density classification.
SCOPE
1.1 This specification covers solid, dry-cast, concrete facing brick 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 S—for 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 brick used in facing applications and other exposures (previously referred to in earlier editions of Specification C55 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).
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 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 having the desired features.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
