I make the material that allows the cement to be completely no go to water or gas migration. Add 600 mesh silica flour to concrete and the psi goes to 11,000, permeability of zero and it resists thermal breakdown to 1200F.
Just wondering, how does it handle crack propagation? You can still make the hardest cement on the planet and microcracks will still grow when under constant pressure. Also, how thick are the concrete casings typically? I'm not trying to contend anything...I'm actually just curious.
