Foamcrete walls anyone?

  • As well as the domes I’m building I’m also converting a pergola into a communal kitchen/laundry.
    I’d like to pour aircrete panels as the non-loadbearing walls. I’ve poured one with the normal block formula to see how solid it is and will let you know the result.
    If it works I’d like to fix it to the frame with a right angle bar at bottom and top, and join them to each other with mortar and fabric.
    But I’d like to know is anyone out built or used aircrete panels?
    Recipes and tips would be gratefully received.

  • @noni We have not had the pleasure yet of doing any projects with aircrete yet. We are researching it a lot and found Honey Do Carpenter has lots of info. He built a regular type shed with aircrete wall panels. Just search Honey Do Carpenter in You Tube.

  • I saw that video, but he used metal panels that he poured the aircrete into and then attached the metal parts together.

    I want to make a big closet to brew beer in with a cool bot in the wall, so am going to try to do some aircrete panels and see if I can work with them. First one today!

    How did yours turn out, Noni?

  • @noni I’ve only poured the full aircrete panel. We’ll do the one with reinforcing this weekend and compare them after two weeks. Illl let you know how they go.

  • I would love to hear how that turns out. I was thinking a lego type style that fits together might work well? for walls I mean so you don't have to use the studs. Honey Do Carpenter did that to suffice local code requirements.

  • @noni Hello I am actually pouring 32"x 36"aircrete panels to add to the exterior of my house. The mix I'm using is to make ten gallon aircrete panels. Hydrated lime (19.201 ounces) Portland cement ( 30 lbs) water ( 16 lbs) I'm using my little pig foam generator and Drexel as the foaming agent. The panels are reinforced with a fibra tape product as well but you could also use hardware cloth. This is a link the the video I made of the process. Youtube Video

  • Just curious about the fiberglass mesh... I'm not sure the price difference between that and the roofing polyclothe. I would bet you could use the polyclothe as well, and maybe add a layer on top while it was still wet. Maybe that would help keep the blocks from crumbling while handling them to mortar them together.

  • @upwinger I actually used the fiberglass mesh for two reasons. One a subscriber to my YouTube channel asked if the could use it so I gave it a shot and it works great! The second reason was to see if it was easier to work with than the hardware cloth I was current using and it was. But to your point next I'm going to try some polyester weed control fabric for my next two panels to see how that goes. It's the closest thing to the apoc roofing fabric that I can get near me. But I've been told it works just as well.

  • @little-pig-store is be interested to see how the weed fabric turns out as I was looking at this as an option to reinforce as I can’t seem to source the roofing fabric locally.

  • @little-pig-store Fiberglass mesh looks amazing. But the cost here would be 10 bucks for a 2x3 foot panel :( But I know cement sticks to glass just like rock. where it doesn't stick to organic materials like wood and it doesn't stick to plastic so i'm not sure why polyester material is working for people. I have not tried it. I'm trying to use pink fiberglass bats because i have them. So far it sticks but i've not found a way to mix it in. I just gums up my mixer. Have you looked into or tried calcium aluminate cement?

  • Honey do Carpenter build a shed using aircrete slabs. Check it out on youtube

  • @little-pig-store how did the weed mesh work out? I have been using hessian (known as burlap in the US) as the fabric but learnt that it could be subject to wicking or rot so I want to put a second, inert layer over it. Weed mesh seems a likely contender. But advice would be welcome.
