Building a CEB project in Midland, Texas in August 2006A compressed earth block ( CEB), also known as a pressed earth block or a compressed soil block, is a made primarily from damp compressed at high pressure to form blocks. Compressed earth blocks use a mechanical press to form blocks out of an appropriate mix of fairly dry inorganic, non-expansive.
If the blocks are stabilized with a chemical binder such as they are called compressed stabilized earth block (CSEB) or stabilized earth block (SEB). Typically, around 3,000 psi (21 MPa) is applied in compression, and the original soil volume is reduced by about half.Creating CEBs differs from in that the latter uses a larger formwork into which earth is poured and manually tamped down, creating larger forms such as a whole wall or more at one time rather than building blocks.
CEBs differ from in that the latter are not compressed and solidify through chemical changes that take place as they air dry. The compression strength of properly made CEB can meet or exceed that of typical cement or mud brick. Building standards have been developed for CEB.CEBs are assembled onto walls using standard and techniques. The may be a simple made of the same soil/clay mix without aggregate, spread or brushed very thinly between the blocks for bonding, or cement mortar may also be used for high strength, or when construction during freeze-thaw cycles causes stability issues. Are shaped to be interlocking. Contents.Development CEB technology has been developed for low-cost construction, as an alternative to adobe, and with some advantages. A commercial industry has been advanced by eco-friendly contractors, manufacturers of the mechanical presses, and by cultural acceptance of the method.
In the, most general contractors building with CEB are in the Southwestern states:, and to a lesser extent in. The methods and presses have been used for many years in, and in.The Department of Water Affairs and Forestry considers that CEB, locally called ' Dutch brick' is an appropriate technology for a developing country, as are adobe, rammed earth and cob.
All use natural building materials.In 2002 the International Institute for Energy Conservation was one of the winners of a for a project to make an energy-efficient Dutch brick-making machine for home construction in South Africa. By making cheaper bricks that use earth, the project would reduce housing costs while stimulating the building industry.The machine would be mobile, allowing bricks to be made locally from earth.Various types of CEB production machines exist, from manual to semi-automated and fully automated, with increasing capital-investment and production rates, and decreased labor. Automated machines are more common in the developed world, and manual machines in the developing world.Advantages There are many advantages of the CEB system. On-site materials can be used, which reduces cost, minimizes shipping costs for materials, and increases efficiency and sustainability. The wait-time required to obtain materials is minimal, because after the blocks are pressed, materials are available very soon after a short drying period. The uniformity of the blocks simplifies construction, and minimizes or eliminates the need for mortar, thus reducing both the labor and materials costs. The blocks are strong, stable, water-resistant and long-lasting.
CEB can be pressed from damp earth. Because it is not wet, the drying time is much shorter.
Some soil conditions permit the blocks to go straight from the press onto the wall. A single mechanical press can produce from 800 to over 5,000 blocks per day, enough to build a 1,200 square feet (110 m 2) house in one day. A high performance CEB press, of design, named 'The Liberator', can produce from 8,000 to 17,000 or more blocks per day. The production rate is limited more by the ability to get material into the machine, than the machine itself.

Shipping cost: Suitable soils are often available at or near the construction site. And CEB are of similar weight, but distance from a source supply gives CEB an advantage. Also, CEB can be made available in places where adobe manufacturing operations are non-existent. Uniformity: CEB can be manufactured to a predictable size and has true flat sides and 90-degree angle edges. This makes design and costing easier.
