AirCrete Form box
I created this box from youtube videos I have seen. On my next pour I will try and take some pictures, if there is any interest in this. After adding the foam to my cement. Roughly 42 to 45 gallon line on my drum. Pouring it into the form I end up with about a gallon left, more or less.
The computer says this form holds 37.4 gallons.
To help with sealing the panels. I used window weather strip material (don't use the foam material). I put it on the three sides of the end panels and just on strip along the bottom of the side panels.
I end up with 12 blocks, 4" thick x 12" x 15". I have been using cat-fish line from the fishing section in the store to cut the blocks. Its rated at 150 lbs.
I did it this way so I can tell if the hole batch I mixed was good or bad. I have trouble when I mix batches together in one form. Doing this by myself.
I'm interested to see photos.
You must have Adobe Acrobat Reader to view this.
This is a 3d PDF file. you will have to download the file and Launch Adobe Acrobat Reader / File Open. Open the file you downloaded.
If you have never opened a 3d PDF file at first the screen will be blank. Click anywhere in the page. A box should come up at the top about enabling 3d content. Click trust.
After that click in the page again. A stop watch icon should appear (loading file), and shortly after the 3d Model should appear.
A 3d Tool bar should also appear. Hold the left mouse button down to rotate. The wheel or right button will zoom in and out.
@jon-bagpipes After thinking about this I realized that some folks may need to open the 3d model on a tablet or other device.
I found this one in the Play Store that will open the 3d pdf file on my "android device". I do not think it has a measuring tool like the acrobat reader does on the computer.

Let me know what you think. If I create any additional models I may share them here.
This is so awesome! I had similar ideas about making custom molds. In particular, if you're building a geodesic dome in particular, have pre-molded edge angles and shapes would be extremely helpful as they are quite complicated and unique
Have you considered doing this for a geodesic dome shape? Also, I always wondered (or was concerned) that having only a small amount of surface exposed to air may cause issues with how the concrete hardens (cracks, variable hardening, ... dunno)... do you see an issues given the small amount of exposed aircrete while drying?
@zander Some photos from this weekends pour.
I have made modifications as i am going along. Had to move hinge on the side to make sure the string would go around them.
You can see I try and put more on top, just because of it collapsing just abit. I don't level it off, suppose I could. Wouldn't hurt anything if I did. You can see I have already cut it and opened the panel.
Great photos. Thank you!
