Another aussie oven getting started
More progress on my Pompeii:-
To be sure I narrowed the centres for rebar to about 10 inches, and poured a 4 inch structural slab.
I scored to perimeter of the slab, to bond the layer of concrete I will eventually pour as a border around insulation layer.
The vermicrete was interesting. I tried the slurry mix method and it went too lumpy, so I reverted to the standard dry mix method, but reduced the ratio to about 8:1. I made a drill mixer to get it started, then finished mixing by hand.
.......more to come

I know what you mean about the Vermiculite. I experienced a similar situation and ended up with I think from memory a 1:6 ratio.
Seeee my information at :

If you are building an igloo pompeii oven, you will experience even more problems with your insulation layers going over your themal blanlet.
I had a few hickups until I found a solution which is here:
permalink #10 where I added a little fire clay to make it stickier and easier to work, especiall rendering the bottom vetrtical areas.
