It really is amazing, you can build a whole 2-story house out of it quickly using polymer-based glue instead of mortar, only using traditional reinforced concrete in some critical places. Was quite popular in russia, last I checked. Unfortunately hard to find in some better CIS countries.

Yes, about 60% of all new single-family homes are built out of AAC in Russia. It's also very common as an infill in reinforced concrete frames, like blocks of flats.

There are AAC factories in Ukraine, Belarus, Kazakhstan that I know of. The rest are probably too seismically risky to be major AAC markets.

You can also build brick walls without mortar, some of them even contain insulation, you just need to plaster both sides and you're good to go. Porothern dry fix is a good example

I had the choice between aircrete and that for my house and went for good ol bricks instead

So they buy preforms, or they mix it themselves and pour into forms?
