Your outgassing in a small room elicited a well appreciated laugh from me. Reminds me of the chef friend at my 4th of July barbecue who, when asked if he wanted any beans replied " No thanks I'm working near the grill". As for outgassing cement, I have had that concern and worked to decrease use of portland as much as possible. There are so many ways to look at it. We leave a footprint no matter what we do. In primitive times folks just lived with what they could gather or hunt, paying it back regularly as manure and ultimately in human fertilizer when they died. There are so many things we just have to come to grips with. We didn't create the situation and there isn't much we can do to change it so we just have to decide what course our consciences will allow us to take. As for me, I've relaxed my standards a lot. After a year of non-activity (thanks to the code officials) I"ve had time to come up with a plan and I'm so happy that it includes papercrete. So I'll keep you posted. I'm just lining up my workers and drafting the plan. I will make some concessions resulting in more use of cement than I have been comfortable with but .....after all is said and done we can either live in an apartment or other substandard situation, or we can do whatever it takes to live in our own self-made homes on our own chunk of earth. It may not be the absolute ideal but it will be as close as we can get it. We do our best and must appreciate ourselves for our efforts.
Sincerely, Judith

Ernie already mentioned the manufacturing process of cement (that's
portland cement, the powder that is a component of concrete.)
Whether someone considers it a major component is clearly open to
interpretation. I personally would call it "significant" but not
major. Keep in mind that lime (the plaster component, not the
citrus) production produces similar gases.
Concrete does outgass very small amounts of things, but it also very
slowly absorbs some gases too. This is absolutely trivial as it
pertains to global warming.

You really don't want to hear my gut reactions... when I have those
reactions in a closed room, people tend to evacuate the room quickly
and hold their noses on the way out.
ohhhhhhhhh..
