Brick Flashcards
A masonry unit of clay, formed into a rectangular prism while plastic and hardened by drying in the sun or firing in a kiln
Brick
Brick made for general building purposes and not specifically treated for color and texture
Common Brick, Building Brick
Brick made of special clays for facing a wall, often treated to produce the desired color and surface texture
Facing Brick, Face Brick
Designation indicating the permissible variation in size, color, chippage and distortion allowed in a facing brick unit
Brick type
Facing brick suitable for use where minimum variation in size, color range and high degree of mechanical perfection is required
FBX
Facing brick suitable for use where greater variation in size & color range is required
FBS
Facing brick suitable for use where particular effects are desired resulting in non-uniformity of bricks
FBA
A designation indicating the durability of a brick unit when exposed to weathering.
Brick grade
Brick suitable for exposure to moderate weathering, as when used above grade on surfaces unlikely to be permeated with water in sub-freezing temperatures.
MW
Brick suitable for exposure to severe weathering, as when in contact with ground or used on surfaces likely to be permeated with water in sub-freezing temperatures.
SW
Brick suitable for exposure to negligible weathering, as when used as a backup or an interior masonry.
NW
The weight of water absorbed by a clay masonry unit when immersed in either cold or boiling water for a stated length of time, expressed as a percentage of the weight of the dry unit.
Absorption
The ratio of the weight of water absorbed by a clay masonry unit immersed in cold water to the weight absorbed when immersed in boiling water, indicating the probable resistance of the brick to the action of freezing and thawing.
Saturation coefficient
The weight of water absorbed by a clay masonry unit when partially immersed for one minute, expressed in grams or ounces per minute. Aka initial rate of absorption.
Suction
A white, powdery deposit that forms on an exposed masonry or concrete surface caused by the leaching and crystallization of soluble salts from within the material.
Efflorescence
The process of forming brick by molding relatively wet clay having a moisture content of 20-30%
Soft-Mud Process
Brick formed in the soft mud process with a mold lined with sand to prevent sticking, producing a matte-textured surface.
Sand-Struck Brick
Brick formed in the soft-mud process with a mold lubricated with water to prevent sticking, producing a smooth, dense surface.
Water-Struck Brick
The process of forming brick and structural tile by extruding stiff but plastic clay having a moisture content of 12-15% through a die and cutting the extrusion to length with wires before firing.
Stiff-Mud Process
The process of forming brick by molding relatively dry clay having a moisture content 5-7% under high pressure, resulting in sharp-edged, smooth-surfaced bricks.
Dry-Press Process
A furnace or oven for burning, baking or drying something, esp. one for firing pottery, baking bricks, or drying timber.
Kiln
Firing brick units alternately with too much or too little air to vary their face color.
Flashing
A brick or timber rejected as being of inferior quality
Cull
A brick made of fire clay and used for lining furnaces and fireplaces.
