Can there be 2 stories?

@upwinger That is a very interesting concept. I don't know if it would work, but it sounds like a good idea. I think the blocks could be premade and then shipped. You would have to be careful because aircrete by itself is brittle.

True dat... Im going to make a planter box with interlocking aircrete blocks this year. I just need to buy a paddle mixer and collect a bunch of free pallets.My plan is to make some molds with 2 x4's and plywood.
I was going to try and line the bottom of the mold with wet roof clothe, spray it with a sticky mix of mortar and concrete adhesive using a texture hopper gun, then pour the aircrete into the molds while everything is still wet.
I don't know how well or difficult the blocks will come out of the molds after setting up for a few days.
Does anyone know if there is a way to help with the blocks to slip out of wood molds without needing to unscrew the molds?? Maybe paint the inside surface of the molds with something?? -
@upwinger Some intensely non-sticky adhesive is my best bet also, so I think you've got the right idea. Did you try it yet, if so, how did it go?

No but soon. I have been working on my floors in my house (installed vinyl planks) and painting interior.
I plan on getting a truck load of pallets soon and start the planter box.
I think I will try to make the molds and pour the aircrete in , then skin them with roof clothes after they set up. -

If you or anyone else discovers a way to remove aircrete blocks out of a mold without disassembling the mold, that could be a major advancement. At this point, I think the challenge is still at the level of how to cleanly remove blocks after the mold is disassembled. For me, the idea of removing blocks without removing the sides of the mold is not a consideration.

@Zander So then perhaps the smartest step could be to create a sort of latch on the outside of the mold, so that it can easily be opened, and put back together.
I see I'll have to do some research for what's already being done in this specific field.
Thanks for your answer.
-
@Shivanga Yes, latches are very handy with aircrete molds. They are often used.

I was wondering if a dome can be premade in Tetris like blocks, completely pre skinned and ready to glue together with sticky mortar. I was thinking of ways to make prefab blocks in molds for different sized domes. The blocks can be made and stacked inside of shipping cotainers to be shipped anywhere in the world! Then the container can be used to live in while the dome is constructed!

@Zander Does lining the mold with a vinyl sheet work?
-
@Kia-Nasseh Lining aircrete molds with thin plastic sheets is a common practice. The use of vinyl, even ultra thin plastic kitchen wrap, is very helpful especially if the plastic is then coated with oil.
