Research compressed earth bricks


Blocks of earth produced manually by throwing wet earth into a formwork are called “adobes” or “mud bricks” or “sun-dried earth blocks”. When moist earth is compacted in a manual or powered press, the resulting compressed elements are called “soil blocks”. In their unbaked state, bricks produced by an extruder in a brick plant are called “green bricks.” Larger blocks, compacted in a formwork by ramming, are called “rammed earth blocks or compressed earth blocks (CEB)”. If these blocks are interlocking, they are called “ICEB: interlocking compressed earth blocks”.

The local population in developing countries are often sceptical towards building with earth. They have a higher regard for modern materials or building techniques like burned bricks, cement blocks, etc. because they are much stronger and more resistant against the impact of water (rain is an important factor for the degradation of the houses). CEB’s represent a considerable improvement over traditional earth building techniques. When guaranteed by quality control, CEB products can very easily bear comparison with other materials such as the sand-cement block or the fired brick. Hence the allegiance it inspires amongst builders and end-users alike.
