Another aussie oven getting started

[Rivernook]

Hi,

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

Hi agin,
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.

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:
