Sure does cut easy.     The air crete also is much harder than before.     when it burns it does not get hot.

Testing the 3 inch riser out.   I can put my hand on the aircrete when it is going full tilt.

Cool!
I make perlite concrete, it cuts  this way as well.
I build in slabs and join them together.

Awesome...    

I have been thinking about putting pipes in the forms so that they would just slide into each other when I want to join them.

I am thinking of adding perlite to the air crete.

I'm not sure if perlite would add anything to aircrete.
Perlite is cheap and full of air,  but not as cheap and airy as a soap bubble!

The peg and slot idea is  good one.
I to help anchor the pipe would probably wire mesh to it,or run self tapping screws into it,or both.
Metal,even buried in the 'crete, could corrode significantly.
Basalt rear and mesh would fix that,  but I prefer locally available matirials,and I can't find it around here.

Thus far I have lined a junked file cabinet with the slabs,  using neat(strait) cement to merge them with each other to form my firebox.
I used some inserts in the forms in an attempt to form details like the port.
Next time I will just use my handsaw.

Today I started thinking you know people make rocket stoves out of cement blocks, what if those blocks had ceramic fiber inside of them?

I reflected on Matt Walkers case that he makes his riser out of.    Ceramic fiber sure changes the rules of the game.
