Nothing to do with soap, but do you know about this?

Rice-husk stoves - Appropriate technology: Journey to Forever
This stuff is great! We're using it to build charcoal-burning stoves,
it's an excellent insulator. Have a look at this picture:

Those coals are really hot!
Reduced strength, as you say, but we find that a mix of 1:3 up to 1:1
cement to rice husk ash by weight is pretty strong, and since the RHA
is much lighter than the cement, in fact you don't use a lot of
cement. It's a bit like pumice or something. Doesn't weigh very much.
The rice husk burner works very well, but if you want to put it in a
55-gal/200 litre oil drum, as we did, you'll have to make the cage
slightly smaller.
Hi,
I am searching for information on making aerated concrete. For those
interested, basically foam is added to a mortar mix, and the mortar can be up
to double the quantity, with reduced strength, but added insulation.
This is achieved with an organic soap (from what I have found), but I was
wondering if anyone had seen info on using home made soap?
<http://pelagic.wavyhill.xsmail.com/cellcrete_how.html> is a site I found with
a home made processor
>From my search on the web, protein hydrolisation seems to be the
soap/additive
that is used for making the foam. I have not found any more info on how this
is made though.
Can anyone help me??
regards Doug
(I am interested in making tilt up concrete panels for a building.)
