[Cob] Arches

[Shody Ryon]

Hi Micheal,
Building vaulted and domed super adobe is done in
fabric forms often called earth bag construction, no
wood needed, correction, wood is used to make forms
that are later removed leaving the arch windows and
door spaces and as floors in multi level buildings. I
have not worked with either cob or super adobe.

Would cob work better than super adobe due to portland
cement and cob, when mixed wet, weakening each other
after they dry do to pH reactions?
