Does anyone know why Autoclaved aircrete is autoclaved? From what i can see the Autoclaved bricks are less strong but the non-autoclaved (the stuff we make) seems to flake. The autoclaved bricks break under less stress but they break clean. I'm wondering if that is why they are used as to not have crushed cement dust as I have. Just wondering if anyone knows why because the autoclave equiptment is very costly making the cost of the bricks too high. So why then?

@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?

Anyone have a recipe for a slab floor that is solid enough that it won't flake when walked on?

@Samson-Jones If you have not already tried this. I would say aircrete used directly as flooring will flake off a dangerous to inhale dust. So no, I would certainly coat it with a "milk" layer that includes laytex.

no mesh. Watch this guy to get an idea of what i'm doing. https://www.youtube.com/watch?v=ddedMmuj7xY Its basically this but lego up the wall. the peice of rebar at the top block is secured to the joist with a steal fastener.

@rloten Do you think you could resell this plan and other building inspectors from other provinces would accept it? An architect isn't an engineer. Not that I don't respect them, but i'm always told an engineer needs to stamp it.

@Ignacio-DHOME
Someone took the time write an entire webpage on how this thermal mass doesn't work in Canada. https://www.ecohome.net/guides/1161/do-earthships-work-in-cold-climates/
I'm not sure what they get out of this lie. It totally works here and we have serveral earthship in the northern parts even that are almost completely passive heated in extreamly cold weather i've seen people growing bannana and avocato trees. So yeah. I agree adding thermal mass up here is a great idea. I also think the thermal mass should not be exposed to the cold. I'm so busy with my aircrete panels at the moment but next summer, I'm going to make aircrete tire bricks and fill the tire with aircrete instead of rammed earth. And build an earthship with them. then put the thermal mass on the INSIDE of the tires and the south facing glass. As for coding. no idea. maybe i'll cover the whole thing with pine branches so no one sees it. lol. Just kidding.. kinda.

@Ignacio-DHOME That's the game isn't it. Sad but true. I'm really hoping a group will get together and get an enginer to draw up and stamp a set of plans we can then buy and give to our building departments. Like they did for earthships.

@Ignacio-DHOME Yes i'm weighing my foam. What i'm saying is that no mater what the weight comes out to as long as it's on the lighter side of 100, my aircrete has works. So i've pour with it being about 65 grams and the aircrete was still perfect. I just add a bit more foam. When it mixes with the slurry some of the bubbles collaspe i guess. Anyhow my point is for me the end result is good no mater what the psi. I literally just turn on my air and go and never had too heavy foam yet.

@Ignacio-DHOME Oh ok. So you aren't trying to get the aircrete to pass but the ferrocement. I think that will pass because ferrocement monolithic domes pass (i think). But if you do that, why build the aircrete stucture at all and do what i'm doing with aircrete blocks inside a structure? The ferrocement already creates a air and vapore barrier (assuming it's coated) Or like some other people are doing and put up plywood and pour in the walls.
