Adobe:''This page deals with adobe, the construction material. For information about the software company, see Adobe Systems.'' ---- Adobe is a building material composed of sandy clay and (usually) straw, which can be cast into bricks or shaped directly into walls using wooden frames. Adobe structures are easily damaged by excessive wikt:moisture, but offer significant advantages in hot, dry climates, as they remain cooler than alternatives based on more "modern" materials. It has many similarities to the Cob (building) traditionally used to construct cottages in parts of England, but cob is never cast into brick form, and is also somewhat differently constituted so that it will survive in a wet climate. ''Adobe'' is from the Spanish language ''adobar'' which means "TO PLASTER" and is traceable through Arabic language ''tauf'' to an Egyptian hieroglyph meaning "brick". The word may be pronounced ah-doh-bee or uh-doh-bee. It can refer to either the bricks, the material itself, or an entire building made of adobe. Buildings made of sun-dried earth are common in the Middle East, North Africa, and in Spain (usually in the Mudejar style), but adobe had been in use by Native Americans in the Southwestern United States and the Andes region of South America for several thousand years, although often substantial amounts of rock are used in the walls of Pueblo buildings. This method of brickmaking was imported in the 16th century by Spaniards from Mexico and Peru. A distinction is sometimes made between the smaller ''adobes,'' which are about the size of ordinary baked bricks, and the larger ''adobines,'' some of which are as much as from one to two yards long. In more modern usage, the term "adobe" has come to mean a style of architecture that is popular in the desert climates of North America, especially in New Mexico. Cf. stucco. Adobe, sometimes abbreviated 'dobe, soil, or land can also mean earth, such as sometimes encountered in the San Luis Valley of Colorado which is a hard packed clay. During or immediately after a rain, a road in such land is quite slick, although not muddy as the rain does not penetrate the clay very quickly. ==Composition of adobe== Adobe is a mixture of clay and sand. Too much sand and the material crumbles; too much clay and it will crack. Straw is sometimes, even traditionally, added to the mix when making adobe, but offers no particular advantage. To find the right combination experiment with the materials at hand until your bricks come out right. The same combining of sand and clay is used by pueblo people to make the raw material for production of pottery or even to make molds for the casting of jewelry. ==Adobe bricks== Bricks are made in an open frame, 25 cm (10 inches) by 36 cm (14 inches) is a reasonable size, but any convenient size is fine for your own use. After the mud is put into the frame the frame is removed. After a few hours the bricks are put on edge to finish drying. Bricks should be dried in the shade to avoid cracking. Use the same mixture you use to make bricks for mortar when laying the bricks and for plaster on the interior and exterior walls. Some ancient cultures used concrete for the plaster to avoid rain damage. It is sometimes useful to include occasional pieces of wood as you lay a wall to give something to nail insulation onto, and stone can be used for additional strength. Bricks can be made waterproof by adding emulsified asphalt to the mud. To test bricks for waterproofing immerse them in water for 24 hours. A good brick will not soak up more than about 1.6 mm (1/16th of an inch) of water. To test for strength, drop a finished brick from a height of 0.9 m to 1.5 m (3 to 5 feet) to see if it breaks. Sometimes if the sand is too fine, the finished bricks will be weak. The biggest structure ever made from adobe (bricks), was the Bam Citadel, which suffered serious damage, up to 80%, by an earthquake on December 26, 2003. Other large adobe structures are the Huaca del Sol in Peru, built using 100 million signed bricks, and the ciudellas of Chan Chan, also in Peru. ==Thermal properties== Because an adobe wall, either made of bricks or using a rammed earth technique, is quite massive it will hold heat or cold. That means insulation needs to be put on the outside of your wall so once the wall is warmed up it will maintain the proper building temperature. A south facing adobe wall may be left uninsulated in order to collect heat during the day. It should be thick enough that it remains cool on the inside during the heat of the day but should be thin enough that the heat can be transferred through the wall by evening. Such a wall can be covered with glass to increase heat collection. Used in a passive solar heating home, such a wall is called a Trombe wall. Adobe has a large thermal mass, therefore this type of construction is only good in very southern climates. In northern climates it is almost impossible to heat a home of this type as the heat is leached by the ground and the walls. ==Around the world== AdobeQ Is this the author's own pronunciaton symbol scheme or one borrowed from the source encylopedia. In any case, I think if you use a pronunciation guide you should reference it. As it is, this pronunciation could be construed as a number of things, and therefore, close to useless...:-).. Our usual would be :Adobe/a-doh'-bee/ I believe. :Your worst nightmare ---- Does the article claim that the adobe technique used in Spain came from the Americas insted of the Moors? I don't quite understand. -- User:Davidme ---- "16 mm (1/16th of an inch)". 256mm. That's a bloody big inch :) (One of those is probably a typo). --User:Blades 17:26, May 8, 2004 (UTC) == Suggest 4 possible wiki links and 1 possible backlink for Adobe. == An User:Nickj/Link_Suggester has some possible wiki link suggestions for the Adobe article: * Can link the Middle East: ''User talk:LinkBot'': User:Nickj/Link Suggester/Positive Feedback, User:Nickj/Link Suggester/Negative Feedback, User:Nickj/Link Suggester/Don't link to — User:LinkBot 11:32, 1 Dec 2004 (UTC) :Done.
