(Specification)Standard Specification for Calcium Silicate Brick (Sand-Lime Brick)
Standard Specification for Calcium Silicate Brick (Sand-Lime Brick)
ABSTRACT
This specification covers brick made principally from sand and lime and intended for use in brick masonry. Two grades of brick are covered: grade SW - brick intended for use where exposed to temperature below freezing in the presence of moisture, grade MW - brick intended for use where exposed to temperature below freezing but unlikely to be saturated with water. The brick shall conform to the physical requirements for the grade specified, as prescribed. All units shall be sound and free of cracks or other defects that interfere with the proper placement of the unit or significantly impair the strength or permanence of the construction.
SCOPE
1.1 This specification covers brick made principally from sand and lime and intended for use in brick masonry. Two grades of brick are covered:
1.1.1 Grade SW—Brick intended for use where exposed to temperature below freezing in the presence of moisture.
Note 1—As a typical example, brick used for foundation courses and parapets in the northeastern quarter of the United States should conform to Grade SW.
1.1.2 Grade MW—Brick intended for use where exposed to temperature below freezing but unlikely to be saturated with water.
Note 2—As a typical example, brick exposed in the face of the wall other than parapet or foundations, or brick intended for structures located in regions of the United States characterized by less severe frost action or by drier climate than is found in the northeastern quarter of the United States should conform to Grade MW.
1.1.3 When the term brick is used in this specification, it is understood to mean brick or solid masonry units.
1.2 If brick having a particular color, texture, finish, or uniformity is desired, these features shall be specified separately by the purchaser.
1.3 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.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
