To create this article, 24 people, some anonymous, worked to edit and improve it over time. Stretcher bond is the one in which all the bricks are laid as stretchers on the faces wall.
As per availability of masonry materials and units, masonry is divided in following types. Brick is made from clay or shale and fired in a kiln at approximately 2000 degrees Fahrenheit to fuse the particles together. stylo brick – 3&5/8” x 7&5/8” x 7&5/8” To learn more, including how to classify buildings with insulation or slow-burning materials, read on. 6- Zigzag bond. Clay and/or shale in a soft-mud process is forced either by hand or machine into a wood mold. ASTM c216 includes a map of the United States showing a weathering index for all regions and has grade recommendations depending upon the weathering index of the region where and how the brick will be used. So, a post office could go into a masonry building or a wood frame building. In this bond, the bricks are laid in zigzag position as shown in the figure. Here is the list for how good bricks are identified at construction site. Some clays when fired burn as a buff color while certain additives to the clay mix make the brick a brown color. Almost all colors are available. This type of bond is not so strong as compared to Engish bond, but it is more attractive. Does the storage material inside a warehouse affect the classification of the building? Determining a building's construction type is dependent on quite a number of different factors and requires a keen eye for detail. These bricks are crushed and used as aggregates for making of concrete. The brick is as popular in older days and as modern days as it has low cost and durability. % of people told us that this article helped them. roman brick – 3&5/8” x 1&5/8” x 11&5/8” On frogs, the wire cut bricks are avoided. In header bond brick masonry all the bricks are arranged in the header courses as shown in Fig-2. There is no additional fire rating in type A, and some non-combustibles are used in the construction of type B. In the brick of size 190 mm × 90 mm × 90 mm, 190 mm × 90 mm face is the stretcher.
3- English cross bond. This is another modified form of English bond.
It gives a more pleasing appearance. All tip submissions are carefully reviewed before being published.

To build any structure, the material is quality should be good. The bricks which are over-burnt and due to this these bricks are brittle.
Other conditions that lead to classification as frame construction include: Metal walls or floors sheathed with combustible materials, Metal floors or roofs with combustible insulation or ceiling material attached to the underside or within 18 inches (45.7 cm) of horizontal supports, Composite assemblies of noncombustible materials with combustible materials, performs well in Earthquake areas – can move, may include enclosed spaces where fire can spread undetected, concrete — either reinforced or non reinforced, note that exterior bearing walls may also be any noncombustible materials with fire-resistance ratings of not less than one hour, floors of 3 inch (7.6 cm) wood plank or 4 inch (10.2 cm) laminated plank, both surfaced with 1 inch (2.5 cm) flooring, roof of 2 inch (5.1 cm) wood plank, 3 inch (7.6 cm) laminated plank, or 1-1/8 inch tongue-and-groove plywood deck, wood column supports not less than 8 inch (20.3 cm) x 8 inch (20.3 cm), wood beams or girders not less than 6 inch (15.2 cm) x 6 inch (15.2 cm), or protected metal, floors and roofs of combustible materials subject to damage by fire, buildings with exterior walls, floors, and roofs of noncombustible or slow-burning materials, building supports of noncombustible or slow-burning materials, noncombustible or slow-burning roof decks on noncombustible or slow-burning supports — regardless of the type of insulation on the roof surface, contains steel, which loses strength at high temperatures, uses slow-burning materials that do burn — adding fuel to a fire, buildings with exterior walls of masonry — not less than four inches thick, or, buildings with exterior walls of fire-resistive construction — with a rating of not less than one hour, and, noncombustible or slow-burning floors and roofs — regardless of the type of insulation on the roof surface, Uses floors and roof supported by superior exterior bearing members that provide for stability and are less likely to collapse during a fire, Uses unprotected steel for interior members of floors and roof, and steel loses strength and becomes less stable and more damageable at high temperatures, Uses slow-burning materials that do burn — adding fuel to a fire, Buildings with exterior walls, floors, and roofs of masonry materials described in the definition of fire resistive (Construction Class 6) — less thick than required for fire-resistive structures but not less than four inches thick, or, Fire-resistive materials with a fire-resistance rating less than two hours but not less than one hour, allows greater height and area than other construction classes, uses load-bearing members or assemblies that resist damage from fire, solid masonry, including reinforced concrete not less than four inches thick, hollow masonry not less than 12 inches (30.5 cm) thick, hollow masonry less than 12 inches (30.5 cm) thick, but not less than eight inches thick with a listed fire-resistance rating of not less than two hours, assemblies with not less than a two-hour fire-resistance rating, reinforced concrete not less than four inches thick, Horizontal and vertical load-bearing protected metal supports — including pre-stressed and post-tensioned concrete units — with not less than a two-hour fire-resistance rating.
A piece of brick which is used to close up the bond at the end of brick courses is known as closer and it helps in preventing the joints of successive courses to come in a vertical line. In this alternate courses consist of headers and stretchers. For a clear understanding keep watch on the image, I have drawn below. References. Waterstruck brick have their own special finish from the folds of the wet clay coming out of the wood mold along with the irregularity of molded brick to begin with. Sand Molded brick are brick that have been produced typically in a wooden mold.
