Pumping Aircrete overhead?
-
@ach2oman Hi! domegaia recomends peristaltic, piston, and screw/(auger style) pumps, and NOT trash pumps. i think trash pumps and diaphram pumps will collapse the foam bubbles. click this link to domegaia Aircrete FAQ Page and scroll down to or search in page for the question "How far can AirCrete be pumped?"
or copy and paste link text below:

I know its an old post but hope this helps. im doing a monolithic flat roof pour in the near future.

What about something like this?

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.
