Well, no cement is "healthy" for aspiration. When they say healthy or not, mostly they are talking about how concrete production generates CO2 emissions during the process. Megnesium Oxide concrete on the other hand traps CO2 while it cures, so it is considered better for the environment. It is also stronger and lighter so you can make thinner walls, but is it much more expensive and difficult to find,at least here in the USA. Magnesium concrete is what the piramids and other millenial buildings are made of. Remember that you can put another thin layer of concrete over the foam, and then as with any house, you are expected to paint it with several layers of a good epoxy or acrilic paint, that once cured should not exhaust any fumes at all.
I'm very interested in what you discover. I've also looked at AirKrete and Allied Foam Tech. I tried adding wood glue to the foaming agent and several other additives. Nothing worked any better then detergent. Please keep us posted on your progress. Thanks
Hi All, I just got my gallon of Drexel FM 160 foam agent. I have been experimenting with Ivory Dish liquid and 2x Dollar General concentrate. I got some good looking solid blocks with the Ivory. The Dollar General 2x concentrate made good looking foam but it evaporated quickly and I got horrible crumbly concrete out of it. This Drexel foam makes beautiful rich foam and it lasts a LONG time on the ground. I can tell a difference how it mixes with the concrete. It looks like I will get great block out of it. Stephen
Thanks Hajjar. Is it necessary to use fiber reinforcement in the floor pour? I have been told that fiber in the concrete is stronger than laying wire mesh in the concrete. I am wanting to prevent cracking.
Great PDF! Thank you FoamAir for the walkthru. We are equally excited about this material and its potential for long-lasting, economical, and beautiful housing. Seems like we are using the proper ratios based on what you mentioned in the PDF which matches up with what is described through Domegaia's videos and website. I suspect the issue might be with our well water source so we are going to try again using the Seventh Generation dishsoap with Reverse Osmosis filtered water from our food co-op in the little dragon.
The volumetric ratio between (Water):(Seventh Generation Soap) is 35:1 as posted on Domegaia.com.
For the (Water):(Drexel Foam Concentrate) it seems that the ratio might be 160:1?
What ratio would you recommend for the (Water):(Drexel Foam Concentrate) to make AirCrete?
Thank you for your support, it is greatly appreciated.
