Hi everybody.

Guys, would you think any of this can be usefull for casting rocket burn tunel and heat riser?

Or even higher temps?

first off it is not concrete it is a castable refractory. It should not have any portland cement in it or a very small percentage to speed up the initial setting up. And yes it should work. typically the higher alumina better.

Thanks Kent.

Well, you know i'm French, so, sometimes i get lost in translation. I know that it hasn't any portland in it. The cement they put in it is "ciment fondu", melted cement. And in french, we say beton, for both kinds of mixture, either normal concrete, or castable refractory.

Is it hard to use that castable?
