I have just started building the base for a pizza/food oven in my garden in the UK, with the dome 1.9m (75") in diameter.
Initially, I was going to create a dome out of pumice reinforced with Basalt Rebar. However, I have chickened out as I haven't n come across someone who has used a pumice concrete for a dome.!!!!
Instead, I intend to use pumice as an insulation for the floor and for the dome.
The dome will be made of Victorian red bricks instead of fire bricks, since firebricks are very expensive for the amount I need.
I am aiming to have the dome internal height from floor around 90cm (36") and the door will have a double arch with chimney chamber 60cm in width in between.
Questions:
1- Is the gigantic dome too low?
2- I already have 60Kg of fire cement, any idea if I need to mix it with sand or should the fire cement be used on it's own?
3- Shall i go for the fire cement ? or the a 3:1:1:1 (sand: lime: portland: fire clay)?
4- If anyone has tried creating pumice dome, please feel free to pass on your thoughts?!!!
