How good is concrete with fire ?
I would like to build a small covered fire pit in my backyard. The pit will be covered all around with concrete and will have two openings: one in the front and a smaller opening in the back for smoke release. How good is concrete if used this way ? If not good, can someone recommend a better material that would withstand heat better than concrete ? Thank you

Concrete reacts to direct flame by explosive spalling. You will want to line the pit with refactory brick.

There is also a high temperature resistant cement, but it is very costly and difficult to get. We used it for the protection of rock under rocket test stands because of the ability to go over the contours and free form.
If you are talking about predictable cirves and staight surfaces, refractory brick would be O.K.
