Mason Brick

For rammed earth, hemp herds or hemp seed, lime, and mycelium cook. 150x75x50 mm Untested but here is the information I could find. "Ah, clarifying with mortar: these hemp-lime-mycelium rammed bricks (~0.5-2 MPa strength, like typical hempcrete) in standard masonry bonds (lime mortar for compatibility) could safely stack into load-bearing walls ~3-6m tall (1-2 stories) with 300mm+ thick walls, light floors, good foundation, and proper curing/bonding. Taller risks base crushing or buckling without rebar/stabilizers. Engineer it & check local codes for real builds—super sustainable idea!"
