Calls for an experiment.
Somewhere in this rabbit hole you guys have lured me into, I watched a video of a guy who poured a circular footing 14' ish and then plopped a tyvec air-form on top of the foundation, draped fiberglass mesh, sprayed a layer of "latex concrete" over the whole thing, let it cure, then laid chicken wire over the whole thing and sprayed another layer of concrete. Reinforced 14' dome for like 5k (probably mainland prices so 10k here) and it took a few days. He claimed this would be "up to code" and could be permitted in most locales. With your equipment you probably are half way there already.
EDIT* found the vid: https://www.youtube.com/watch?v=DVk6xNFduH4&ab_channel=AircreteHarry
EDIT#2 in this vid he shows a double wall shell made of stucco into which he pours aircrete. https://www.youtube.com/watch?v=-90FPThl0ak&ab_channel=AircreteHarry
Haven't seen anyone spraying thickened aircrete yet. Maybe you can make an Aircrete Dobanion video! What do you think would thicken it enough to make it work on an airform?
And thanks for the response on the aircrete/Rastra idea. Seems a bit more local/green/economical that way.
