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.

Are you pouring directly into vertical cavities, or horizontal panels then lifting them into vertical spaces?

I'm in there area and interested to hear if you ever get your project going.

That ratchet strap is a great idea!

@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.

Thanks Zander! Saving this one for future reference.

Another effective, low cost solution. Terrific!

Terrific idea -- have you had the chance to try this setup yet?

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.
