I have a client that wants to build a “green” home but they will not use anything that has polystyrene in it!

I am researching AAC block and poured in place cellular concrete. The poured in place makes a lot of sense because you are not hauling the AAC all over the country. Problem is I can find very little information on this subject. And even fewer people that have experience with the process.

Someone out there have first hand experience with pouring cellular concrete?

I am thinking of building forms out of MgO board, pouring and leaving the MgO as finish surface inside and out?

Any help would be appreciated.

AAC by itself is better than brick but not a total solution, you still need insulation. If you look on the above attachment it shows batts being placed in the cavity, they could be fibreglass or cellulose.

Sounds fun.

Be good, if you can not be good be careful.
