I would have said that, but they have a tendency to get cracks in them from earthquakes and arent easy to repair or remodel. I have a friend in Israel who has a house with this problem. Its really expensive to fix and the fixes arent lasting that long.
Aircrete, if it was more resilient, might get past that, be cheaper and more fixable long term. Also, would be a better insulator. Also, theoretically, aircrete rubble can be crushed and reused to make more aircrete. The blocks could be knocked down for reuse.
So how do we make aircrete more resilient? Latex, fiber, etc?
I am seriously in favor of DIY fixes for sustainability.

One bad thing about recycled plastic is: Much of it will degrade in 1-3 years into tiny particles. If it lasts longer, it may have lots of forever chemicals in it.
polyvinyl chloride, which lasts longer and is stronger, is considered hazardous waste so its not desirable either.
