Have you heard of grancrete? It's a new building material developed by Argonne Lab. And it should be an ideal material for tbhs, especially non-migratory ones. What do you think? How would you design a grancrete tbh?

here's something similar
it was pushed a lot at one time for building yachts
I think they whip air into it to make it lightweight
reguires equipment I don't have to spray it but I think it's possible to trowel it on too
