- This is my first build of a wood fire pizza oven using Castables Refractory cement for the dome, instead of fire bricks, The front arches, chimey and floor are all fire bricks or pavers made to use in woodfire pizza ovens. But the dome is castable refractory cement.
And the food we have cooked in it always comes out so good. The arches flooring and firebricks all mortars, insulation etc were supplied by Field Furance in Wetherill Park sydney
Please leave any questions or comment in the comments section.
Great build!
brilliant job! very well explained and detailed.
Great build. How much refractory castable did u use for the dome? And what thickness did u cast?
@@sonakul100 8 bags , around 80mm
Just a question, would it be okay to mix Vermiculite with refractory cement ??
Well you could but it would just weaken the strength of it
Great build Johnny, I am just ordering my castable and floor bricks how many bags of castable did you need for (I assume) 50mm thick, I am up here in Gods country so I finally sourced everything that I need ( not as easy in Brisbane as it is in Sydney or Melbourne) and will order this week, (I have guestimated 8 bags but as long as that is not short I will just make the dome thicker
Hey, great video, what floor pavers did you use? And how have you found them with the heat?
Hi they are fire brick pavers so they are make to handle the heat
How did you get the forms for the dome out?
Hi ...I they were in 1/4 pieces and came out but you could just burn them in there on the first burn 🔥 😁
Good job! Nice to see Aust suppliers listed. Did you think about homebrew refractory cement?
No I didnt but maybe next time I build one I might
Brilliant build - what was the overall cost of materials?
About Aus $2G total
How has it been holding up? Doesn't look like you put reinforcement into the castable
Castable is fine no cracks and you are right there is no reinforcement in it ... but it is superstrong stuff
Hi, what kind of concrete did you used for the slab?
Just standard I think 20mpa
Thank you for the response. Does it has to be refractory cement? And does refractory cement could do slab too?
If it is the standard, does it last long because of the high heat temperature of the oven?
Ok sorry the dome is refractory cement for the heat ..which i think is rated to around 1600°c pizzas cook around 600°c ....... the slab under it is just standard cement but has the heat rated floor pavers on the slab ..cheers
Did you mix the refractory cement with anything?
No just straight out of the bag
@@johnnykkkk how much did the bags weigh and how many did you use
@@frankboy619 I would love to know that also
