We were given the task to find a material that Architects could use to make curved shapes in building envelopes. Obviously concrete could be the material to use but my goal was to try and find a material that wouldn’t have a negative impact on earth as concrete destroys the top layer of the earth.
I stumbled upon Rammed Earth, which is exactly what it sounds like, a mixture of moist dirt that is compacted enough until it becomes solid bricks/ sheets. Just like concrete, you can reinforce the rammed earth by infusing structure in the inside of the mixture. The problem with the material is that it must be sealed from airflow because once the rammed earth losses its moisture it becomes very brittle and can easily break under pressure.
The picture above shows the process that must be taken to create rammed earth.
