lol... You don't know what you're talking about. Aircrete is extremely limited structurally and mostly used as a superficial covering instead of brick and or siding. It has the benefit of extremely efficient for insulation while being fireproof. However, it's mostly useless as a structural base in most cases. Which is why most structures made entirely of aircrete look like igloos. Basically both concrete and aircrete are strong in compression, but have almost zero tensile strength and require rebar for these loads. But once compressive loads get high enough, like in multi-story structures, there's no way aircrete can support the loads. Just double checked load strength, Aircrete is can support around 100 PSI in compression, while concrete is typically around 3,000 to 5,000 PSI. Not sure how that'll work in earthquake areas or locations susceptible to tropical storms. But there's plenty of areas that have neither of these issues.
Yes, I'm an engineer and work in Industrial Construction.
@EL CORINTHIAN is completely correct that a 3 story story structure made entirely of aircrete isn't feasible. It'll work with another material providing the required support. Similar to how there's 4" brick facia for aesthetics, with wood, steel or concrete providing support. That's why the large structures you posted are renderings, because no one is ready to use aircrete in those applications yet. I'm sure it's coming though.
That said, there appears to be decent future for it as they work out these issues. I imagine in places like Arizona, it would far superior due to its insulating and fireproof properties. Using it a lower cost pre-cast sheathing for large structures sounds promising, both for cost and insulation.
And congrates on being a typical douche when someone asks you questions... lol.
