While we haven't pumped vertically, we've successfully pumped horizontally by making our aircrete mixing container air-tight, then pressurizing the top with an air compressor so that the mix would flow through a hose attached at the bottom. Doing so seemed to have little effect on the foam, which set fine under the concrete slab we filled beneath.

RE: Pumping Aircrete overhead?

RE: Foamcrete walls anyone
Are you pouring directly into vertical cavities, or horizontal panels then lifting them into vertical spaces?

RE: Need help in USA, Georgia.
I'm in there area and interested to hear if you ever get your project going.

RE: Making easing the steps of making aircrete and molding
That ratchet strap is a great idea!

RE: Geopolymer Aircrete?
@moonrise said in Geopolymer Aircrete?:
Portland cement production creates a great deal of atmospheric carbon waste
While this is true, nearly every building material carries a carbon footprint:
Following the Domegaia recipe yields an airecrete building material that, for a given volume, uses just a fraction of the portland cement of traditional concrete. This significantly reduces its carbon footprint, so that it becomes comparable to many other common construction methods.

RE: Troubleshooting Aircrete
Thanks Zander! Saving this one for future reference.

RE: DIY Cement Slurry Whisk
Another effective, low cost solution. Terrific!

RE: Down-n-Dirty DIY Foam Injector
Terrific idea -- have you had the chance to try this setup yet?

RE: Continuous mixer
A method for continuous mixing and pumping aircrete would be the tipping point that moves this technology from hobbyist projects into mainstream commercial building applications.
I sincerely hope that someone in the concrete industry has realized this opportunity and is working on equipment to solve it.
