Compressed earth blocks require a soil that is 20-30% clay. All clays do not behave the same way (reactivity, mechanical strength, …). The quality of the brick needs to be studied on a case by case basis by conducting laboratory tests. However, most soils are capable of being compressed, the quality of bricks depend on the quality of the soil.

Compressed earth blocks (CEB)
Compressed Earth block System. Compressed earth blocks are masonry units made from rammed earth. As with monolithic rammed earth, a moist soil mix with relatively low clay content (10%–30% is common) is rammed into block forms under high pressure to achieve a desired level of compaction. The soil mix varies by region and builder, but it is ...
