I've seen Dukabour ovens that are made of stone and cement. A fire is lit
inside them to heat the entire dome before they slide the bread loaves
inside for baking.
I'm thinking of doing somewhat of the same thing, but with concrete blocks
and mortar....and maybe some poured concrete as well. It would be for a
different purpose...more of a natural smoker.
Is there a special concrete mixture that holds up to heat?
In general how does concrete stand up to heat. The most extreme heat would
be limited to the fire box and the air would be vented to the smoker where
temps would be around 200 degrees.
Google around for alumina cement. Here is one site:
we had to use some for the floor of an epoxy oven that baked epoxy
inside oil field drill stem. Really set up quick, barely got it
out of the concrete pump once it started to go. Interesting
material. Contact a large local concrete company or boiler repair
company for information about refractory cement, fire brick, etc.
