Maximize strength and ductility
without too much steel
Earthen walls rely on stability and are reliable even without strengths comparable to concrete block or brick walls.
What structural guidelines are there for brittle unreinforced earthen walls?
Reinforced adobe, rammed earth, CEB all have high strength with some ductility.
Reinforced ICEB can have moderate ductility, and cob even more
Conventional earthbag has moderate ductility with low strength.
Improved contained earth (CE) detailing delivers moderate strength with high ductility.
