It never stops amazing me when trying to find materials for the build of my wood fire oven that folks just seem to have a better way of doing things. They take the plans look at it for a second and dismiss them as nonsense. Happend just recently to me when trying to track down some materials but I did take pause with something a supplier of refractory cements, insulations and bricks mentioned or as he put "if I were doing this I would . . . ."
He mentioned a refractory concrete they use for shotcrete that rates up to 2500 degrees. Instead of laying firebrick he feels that building a form and pouring the refractory concrete would make more sense. On the face of it, it does seem to make sense, would be cheaper ( 50 bucks for 100# needing 130 # per cubic foot). Firebricks are going for 1.75-2.50 areound here. It rates to 2500 degrees F. and may be faster than putting down over 152 firebricks. Never having done a WFO I have reservations about deviating from the plans however. But in the long run I already am as I am using different insulators and the like.
Has anybody poured their oven floor? If so how has it been working for you? Would you do it again?
How about the other side, why wouldn't you? What are the cons?
