This was reasonable since it is one of the oldest forms of masonry construction, and, in some parts of the world, it is still in use. The process of making these types of bricks involves the use of soil mixed with a fibrous material like straw, or loam. The soil typically contains some sand and silt, but its most important component is clay. The clay acts as a binder holding the rest of the soil together and it sticks the rest of the material to the straw. It is important that the type of clay used is not an expansive clay since it would lead to uneven drying and result in cracking (in Florida this is sometimes called shrink-swell clay). The straw in the brick acts like rebar in concrete; it carries the tension.\n", "\n", "The soil and straw (and sometimes dung) are mixed together, then formed into brick shapes either with a mold or by hand, then left to dry in the sun for at least two weeks or more. Once laid into a wall the surface is typically plastered over with mud. This acts as a sacrificial coating that will protect the bricks when it rains. This coating needs to be periodically replaced to prevent erosion of the bricks.\n", "\n", "Though a more permanent cementitious coating can be applied, this moisture protection requirement almost uniformly relegates the use of mud bricks to dry climates.
