Pore concrete (known as Yton brand) for rocket stove isolation

Hi everybody
I was wondering if there are some experience by using pore concrete as isolation of the burning chamber J? In my experience pore concrete is very easy to cut and shape.

I want to build a baker oven with a rocket stove and it needs to be mobile on wheels. So lightweight materials would be great. I maybe failed in the lightweight attempt already by using 4mm wallthickness steel pipe. But i got it for free🤷🏻‍♂️ Any thoughts are welcome!

Hi Tobias;    
Welcome to Permies!
I've added your post to the rocket oven forum as well.

So you're building a mobile oven for baking?  
Very cool, perhaps freshly baked bread in people's dooryard?

You are wanting to insulate your "core" metal pipes.
I do not know of Yton brand but I do know that concrete will fail over time at rocket temperatures.
Perhaps a mix of perlite and fireclay in a lite metal containment would do the job as well?

Hi Tobias, I dont know what yton is either but I think that in my area, it is what we call themo crete, an aerated cement mix.
I am not sure if coating a metal pipe in a ridged cement based product will work for you, the metal will expend and crack the cement and the pipe will get too hot and wont last very long.
