Can we get some input from any engineers out there? This stuff must have drawbacks or we would be using it ourselves.

“Can we get some input from any engineers out there? This stuff must have drawbacks or we would be using it ourselves.”

It might be a derivative of grancrete, which was invented here by Los Alamos for encasing spent nuclear materials but has been commercialized. Grancrete has a 12,000 psi strength, which is really high for a concrete, so I don’t know how you get to 50,000 psi since steel is 30,000 psi.

Big problem with grancrete is it is too sticky to trowell. That’s why you always have to look at breakthrough claims with skepticism.
