Brick

They may be made clay, shale, soft slate, calcium silicate, concrete or shaped from quarried stone They are used for mansory construction. Bricks are used for building and pavement. They are also used in the metallurgy and glass industries for lining furnaces Common brick, face brick, refractory bricks and glazed bricks. The brick laying techniques are referred to the way that the bricks are used and located to get the best construction. Running Bond: this is the simplest one of the six patterns, consisting of all stretchers. Because the bondhas no headers, metal ties usually form the structuralbond. The running bond is used largely in cavity wallconstruction, brick veneer walls, and facing tile walls made with extra wide stretcher tile Common or American: is a variation of the running bond, having a course of full-lengthheaders at regular intervals that provide the structural bond as well as the pattern. Header courses usuallyappear at every fifth, sixth, or seventh course, depending on the structural bonding requirements. Advantages: brick is cheap

Comparison and contrast:** <span style="color: black; font-family: Arial,sans-serif; font-size: 10pt;">Brick compares favorably with stone as a structural material for its fire-and-weather resisting qualities and for the ease of production, transportation, and laying.

d**. Cause/Effect:** Bricks may be used in construction only in conjunction with mortar, since the unit is too small, too light, and too irregular to be stabilized by weigh

Description: **<span style="color: black; font-family: Arial,sans-serif; font-size: 10pt;">Regular bricks are bonded either as headers (short side out) or stretchers (long side out). Standard modern types provide a ratio of width to length of slightly less than 1:2 to permit a wide variety of bonding patterns within a consistent module, or standard of measurement.
