Air Crete vs Concrete For Raised Beds
I'm a big fan of using concrete bricks, specifically what's called "partitioning blocks", which are regular size but half as wide, to make raised beds.
My current raised beds are just one brick high. Given my decline in physical condition, not big but getting down on my hands and knees is getting more and more difficult at 62, I'd like to increase the height of my raised beds when I move in with my sister at retirement so I can weed from a sitting position. A taller bed would also allow me to experiment with soil additives like Hugelkultur.
That's why I found this Youtube video interesting.
If you know anything about the Romans and concrete, you know that they often added volcanic pumice to the mix to lighten the weight of their structures and bricks. Air crete does the same thing, but with organic material like hay or straw.
Larger blocks, especially ones that have an inter locking mechanism, and which I could bond together, might be the way to go. Not sure if I'd save any money, the partitioning blocks if I remember are under two bucks a piece but might be better even if more costly.
Has anyone worked with lighter versions of concrete or poured your own
