@Jim_Scan Aloha,
What we call hardware cloth here is actually a silly name for it. it's like a wire mesh similar to chickenwire. it comes in difference gauges. I use 19 or 20 gauges. I did tests of 2 parts water, 1 part cement, 6 parts perlite. and a test of 2 water, 2 cement and 5 perlite.
The second one was obviously stronger and since i was using this as a panel that covers an open hole in the my floor, i liked the strong one for that. The first i will use for my slab.
Their are 2 different sizes of perlite. I like the smaller size. the larger size I use for the garden. The smaller size is better for concrete IMO. I did make some bricks with the larger garden size because I ran out of the small stuff and worked and it gives a cool look.

If you don't have hardware cloth, You could try anything that gives tinsel strength.

I like the large floor tile idea but I think they may crack over time if they are not on a flat solid surface. Even ones on concrete can crack if it's not very flat. Perhaps a clay top would be best but i have little clay in the soil here.

Of course i have read though the domegaia website and much of this forum. I've been trying to get aircrete to work for over a year. I've branched off to use perlite as lightweight aggregate instead of air bubbles and I have much more success and found it easier to use. Perlite is not free, however, but then neither is bags and bags of crumbly not curing correctly aircrete that end up in the garbage. I have so many blocks of attempted aircrete at this point, i think i wasted money on a pump. I'm going with an perlite and cement floor with hardware cloth layed on top and a thin layer of sand cement on top of that. I did a panel test and i can jump on it no support under it and it still doesn't break.

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.
