@zander I will try and make a video on my next attempt. I just built a work bench 4ft x 8ft x 3/4 ply. I am hoping that will be a stable enough surface.
It may be a few weeks though.
Look forward to hearing any feed-back from my pics and/or video.
I'm heading down to my place in Pescadero in a week or three and looking for / considering support / training options my self, and to start my own project in due course. I have a little earthbag experience, but no aircrete as yet, but looking to change that, so let me know if I can be of help / collaboration
Thanks for that, Iggy. I'll try pouring a test section first. I'm filling the chasings for wiring and plumbing at the moment, using regular mortar because I can't get aircrete mortar to stay on vertical surfaces unless I let it sit for 5 or 6 hours before using it. It may have something to do with the cold and damp, here. Do you know a way of making it firmer?
Using large tile on an aircrete slab shouldn't crack if the underlying soil isn't expansive clay or unstable and/or not properly compacted. When tile cracks on concrete it is usually because the ground underneath has moved and buckled the slab.
@Rufus I have the same question. I would say that it's non toxic. The water is the concern though it may just breathe and dry out. Otherwise, a "climate active" product would probably be the best coating inside and out.
@Carolebrdn yes! Try using hot water in the foam mix. This is what we did at the Pt Townsend workshop and it seemed to have success. They had trouble later keeping the water warm, so I think they got an electric water heater like the link below to keep the foam mix warm. You could also keep the foam mix circulating by using the little dragon without any air on and just putting the outlet of the pump back into the top of the barrel. This circulation generates some heat in the foam mix from friction in the movement.
@Ignacio-DHOME Good idea. You have to contend with the particals thou. perhaps wetting it and then shopvac. I'm just thinking it might be better to hepa vacume it up as dust. Wetting it might make it harder. would have someone stand next to me and vacume as i saw. I don't know but it's a discussion no one seems to be having. I know it's not the fun part, but still important. I saw a photo of someone who knelt on his wet slab (trying to screek it) and didn't wash it off and ended up in the hospital for weeks with burns down to the bone. So it's not like it's nothing. I always were a mask but after its cut it falls to the ground where it can easily be kicked back up. I mean the particals don't disappear after i'm finished cutting. I have designated a "toxic" area on my property where we don't plant and animals aren't allowed so I have a place to clean tools and buckets etc, the making and cutting is done is habitable areas.
