it is more dense I believe so is adding more weight to the build but should be perfectly functional, I have no idea on the costs or availability tho.

I had a look at Leca, but went with Vermiculite as it was easier to get hold of.
Leca seemed to be okay to use, so long as it would be the sort made up of many sized particles to lock together. I thought Leca aould be better through not being so open to soaking up the water needed to create the cement slurry. It would soak it up, but not so dramatically. Thereby not needing so long to drive out the water later in the curing process. Its not tried, so i'd say you be the guinea pig. If you don't mind that, and can take a failure, then go for it and report your progress for the betterment of all. Leca would work well in an oven within an enclosure as loose fill insualtion.
The weight issue is only an issue to the base structure, as any Pompeii or Vault oven gets stronger with more load, so long as the bottom cannot move outwards.
Good luck!

I've only ever read about the product, but have always been interested in using the product on a wood-fired oven.
Please let us know how you get on....if you use it.
