Bricks vs Mortar

[Tiggi]

Hi all,

Been reading this forum for a while now and thank you all for the great inspiration. I am planing to start my first build this spring so you'll see lot more of me. For time being I only one question, or more like series of em regarding one topic. Is it possible to build a dome using a mortar (fire mortar, refractory mortar,...etc) instead of bricks? What would be downside of it and would it perform as good as brick dome?

My idea is to create a mold out of sand and use the mortar to create a dome, either single peace or break it down into sections. I would use the steel reinforcement into the construction just to give it extra strength.

Yes there is plenty of info about cast ovens here. Try searching for cast ovens or castable refractory.

I've read lots of post on this subject and definitely interested in building my oven this way. From what I can tell it's lot faster, easier and cheaper. One thing that I am not clear on is the performance of the castable ovens compared to brick ones? Does anyone have any research on this?

If you are thinking about casting an oven, check out IronPony's thread. This is probably the nicest cast oven I have seen. Were I to do this over again, I would think about using that approach
