Process-driven material

The bricks made of the construction site soil without any additives are very loose due to the high sand content of the soil. A sticky rice mix (a) and egg white (b) is smeared onto the surface of the brick until saturated. Both rice and egg white have binding attributes and, despite only being added to the surface, keep the soil mix in place.
