Maximize strength and ductility
without too much steel
Earthen walls are reliable even when strengths are lower than concrete block or brick walls.
Structural guidelines exist for brittle unreinforced earthen walls
When reinforced adobe, rammed earth, CEB have high strength and some ductility.
Reinforced ICEB has some ductility, and cob even more
Conventional earthbag has moderate ductility with low strength.
Improved resilient contained earth (CE) has moderate strength with high ductility.
