What is a brick made of?
An adobe brick is a composite material made of earth mixed with water and an organic material such as straw or dung. The soil composition typically contains sand, silt and clay. Straw is useful in binding the brick together and allowing the brick to dry evenly, thereby preventing cracking due to uneven shrinkage rates through the brick. Dung offers the same advantage. The most desirable soil texture for producing the mud of adobe is 15% clay, 10–30% silt, and 55–75% fine sand. Another source quotes 15–25% clay and the remainder sand and coarser particles up to cobbles 50 to 250 mm (2 to 10 in), with no deleterious effect. Modern adobe is stabilized with either emulsified asphalt or Portland cement up to 10% by weight.
How big are Adobe bricks?
There is no standard size, with substantial variations over the years and in different regions. In some areas a popular size measured 8 by 4 by 12 inches (20 cm × 10 cm × 30 cm) weighing about 25 pounds (11 kg); in other contexts the size is 10 by 4 by 14 inches (25 cm × 10 cm × 36 cm) weighing about 35 pounds (16 kg). The maximum sizes can reach up to 100 pounds (45 kg); above this weight it becomes difficult to move the pieces, and it is preferred to ram the mud in situ, resulting in a different typology known as rammed earth .
What is a puddled adobe wall?
Poured and puddled adobe walls. Poured and puddled adobe (puddled clay, piled earth), today called cob, is made by placing soft adobe in layers, rather than by making individual dried bricks or using a form.

Materials Similar to Adobe
- Compressed Earth Blocks (CEBs) resemble adobe, except they usually do not contain straw or asphalt, and they generally are more uniform in size and shape. When adobe is NOT formed into bricks, it's called puddled adobe, and is used like the mud material in cob houses. The material is mixed and then thrown in lumps to gradually create an earthen wal...
Preservation of Adobe
- Adobe is resilient if well-maintained. One of the oldest known structures in the U.S. is made from adobe bricks, the San Miguel Mission in Santa Fe, New Mexico, built between 1610–1628. Preservationists at the National Park Service of the U.S. Department of the Interior provide guidance on historic preservation, and their Preservation of Historic Adobe Buildings (Preservati…
Traditional Methods of Construction
- To maintain historic and traditional adobe, its best to know traditional methods of construction so that repairs can be compatible. For example, true adobe bricks must be assembled with a mud mortar of properties similar to the adobe. You can't use cement mortar because it's too hard — that is, the mortars cannot be stronger than the adobe brick, according to preservationists. Foun…

Description
Adobe bricks are rectangular prisms small enough that they can quickly air dry individually without cracking. They can be subsequently assembled, with the application of adobe mud to bond the individual bricks into a structure. There is no standard size, with substantial variations over the years and in different regions. In some areas a popular size measured 8 by 4 by 12 inches (20 cm × 10 cm × 30 cm) weighing about 25 pounds (11 kg); in other contexts the size is 10 by 4 by 14 i…
Strength
In dry climates, adobe structures are extremely durable, and account for some of the oldest existing buildings in the world. Adobe buildings offer significant advantages due to their greater thermal mass, but they are known to be particularly susceptible to earthquake damage if they are not reinforced. Cases where adobe structures were widely damaged during earthquakes include the 1976 Guatemala earthquake, the 2003 Bam earthquake, and the 2010 Chile earthquake.
Distribution
Buildings made of sun-dried earth are common throughout the world (Middle East, Western Asia, North Africa, West Africa, South America, southwestern North America, Southwestern and Eastern Europe.) Adobe had been in use by indigenous peoples of the Americas in the Southwestern United States, Mesoamerica, and the Andes for several thousand years. Puebloan peoples built their adobe structures with handsful or basketsful of adobe, until the Spanish introduced them to making bri…
Etymology
The word adobe /əˈdoʊbiː/ has existed for around 4000 years with relatively little change in either pronunciation or meaning. The word can be traced from the Middle Egyptian (c. 2000 BC) word ḏbt "mud brick" (with vowels unwritten). Middle Egyptian evolved into Late Egyptian, Demotic or "pre-Coptic", and finally to Coptic (c. 600 BC), where it appeared as ⲧⲱⲃⲉ tōbə. This was adopted into Arab…
Material properties
Adobe walls are load bearing, i.e. they carry their own weight into the foundation rather than by another structure, hence the adobe must have sufficient compressive strength. In the United States, most building codes call for a minimum compressive strength of 300 lbf/in (2.07 newton/mm ) for the adobe block. Adobe construction should be designed so as to avoid lateral structural …
