Building a CEB project in Midland, Texas in August 2006 Compressed Earth Block often referred to simply as CEB, is a type of manufactured construction material formed in a mechanical press that forms a compressed block out of an appropriate mix of fairly dry inorganic soil, non-expansive clay, aggregate, and sometimes a small amount of cement. Typically, around 3000 psi is applied in compression, and the original soil volume is reduced by about half.
The compression strength of properly made CEB can meet or exceed that of typical cement or adobe brick. Building standards have been developed for CEB. Creating CEBs differs from rammed earth in that the latter uses a larger formwork into which earth is poured and tamped down, creating larger forms such as a whole wall or more at one time. CEB blocks are assembled onto walls using standard bricklaying and masonry techniques. Development[edit] Advantages[edit] There are many advantages of the CEB system.
