There are many videos for home made "aircrete" that even uses dish soap as a foaming agent. What are your thoughts on these? How about if basalt fiber and basalt rebar would be used in combination with such a material instead of metal rebar?

So a mix with air bubbles such as aerated concrete mean it is not good for a long life-cycle without additional exterior protection?

[@TylerLey]

Douglas - There are a lot of challenges with aerated concrete that is directly exposed to the elements. I do think it has many possible uses. There is also problems with transferring loads between reinforcing bar and the concrete.
