Revealing the Potential of Compressed Earth Blocks
Revealing the Potential of Compressed Earth Blocks—A Study in the Materiality of Compressed Earth Blocks (CEB): Lightness, Tactility, and Formability, by Egyptian architect Omar Rabie, documents explorations of the potential of CEB while studying at MIT, The Architectural Association and Auroville.
In these two experimental mock-ups, Rabie explored the different possibilities of bondings using one block—specifically how the shape of the single block influences the block bonding patterns in a stack bond and running bond.
This portion of a wall was built of specially formed interlocking blocks to increase friction to test how high friction masonry wall will highly resist lateral loads in comparison to walls constructed with standard blocks. In this case, the blocks are interlocked in the long direction of the wall. This experiment proved that it is possible to freely form more complex CEBs and build walls with an unusual bonds, like this strong zigzag bond.

Earth Brick Residence
The Earth Brick Residence in Chiba, Japan by Atelier Tekuto is a single story structure comprised of 2,600 compressed earth blocks stabilized with magnesium oxide. The mineral was used for masonry joint for pyramids and Great Wall in China. Its substances are extracted from the ocean or land and can be produced everywhere in the world and resourceful. Also, it is safe as food additive, and harmless enough to return to the ground.
The strength of the bricks is much greater than the traditional sun-baked earth blocks made from animal manure and lime -- a process typically seen in developing nations. The different composition used in this project's earth blocks mean that they surpass Japanese construction standards for strength, one of the most stringent in the world.
The house is the result of The Earth Block Project started in 2008, was developed together with Universities, corporations, and specialists with the idea that construction materials can be made with any soil in the world can be stronger than the existing soil construction materials and return 100% to nature.

Youth Center In Niafourang
The Youth Center In Niafourang, designed by Project Niafourang (three architecture students at the Norwegian School of Science and Technology), was built in Niafourang, a small coastal village in the Casamance region of Senegal. The population of Niafourang is around 300 inhabitants and the village is very poor with a high unemployment rate.
The Youth Center in Niafourang contains a computer room/library and a larger multi-purpose room and hosts programs that create opportunities, jobs and development in the village. An important aspect of the project was to involve the local community in both the building and planning stages, in order to create a sense of ownership and pride in the resulting building.
The walls are built using blocks of compressed sand and a small amount of cement. The blocks were hand-pressed using a local machine with sand shoveled from a nearby ditch. Windows are positioned low on the walls with deep frames, so they can be used to sit in. Steel brackets were custom welded in a nearby village and hold the roof construction. The corrugated aluminum roof juts out beyond the walls to prevent rain from entering the building and creates shady areas to relax.
Underneath the protruding roof, a concrete belt surrounds the building creating a shady platform. The roof extends to include a second floor outside the walls of the multi-purpose room. The second floor is accessible by an outdoor ladder and functions as an extension of the library/computer room or the multi-purpose room. Angled wood planks serve as blinds, preventing both rain and direct sunlight.
