Does have me thinking a bit. Me being the dome guy I am, and owning an airform, I always figured whatever I did had to be spray applied. Aircrete is generally regarded as being so fluid before setting, that the only way to make it useable was to pour into forms, making bricks of various sizes. But, I have access to some interesting thickening compounds which could made aircrete "stand up" in such a way as to be applicable to a airform. Calls for an experiment.

from what I read, plain water+concrete+foam air crete is not real strong.

Does anyone have experience with aircrete with the latex additive?  I have used the latex liquid in other mortar applications and was impressed.  Its a little expensive, however.
