I love Pizza... and in NYC and the burbs there are places that have legacy ovens that operate at insane temperatures.... and can cook a pie in 2-3 minutes....
Patsies, Grimaldis, Lomardis, can crank out pies...and every neighborhood has a Pizza joint that provides a good pie...
On edit... Omitted Tottonos
In any event.. I want a blast furnace type oven of my own...
So I designed a refractory concrete mix.... using perlite and silica as coarse and fine aggregates with portland cement and another cement, and stainless steel fibers as reinforcement...
I wont be grouting or cementing any of the components of this oven together... I.E. Ill be able to lift the arch off to give the floor a good cleaning...
The mix I designed is 85 pcf the arch is 1.3 cubic feet.. I can move that around...
Stainless reinforcement
inner mold or formwork...
Outer formwork..
The ports in the end dam are where the concrete mix gets into the mold (form)
Completed form
A dam to prevent spillage while I am filling the mold...
I hope to fire this oven up in a week or so with some small fires..
