Fuck aircrete. My house has aircrete blocks in the extension and you need special expensive wall plugs to attach things to it that are rated to a grant total of 25kgf.
Because nobody would want to actually hang heavy things on their wall right??

> 43kgf (shear load)
That seems really low for shear. The M8 Rigifix say 245 kgf for 1mm displacement in shear.
Also I slightly misremembered the rating for pull-out - actually in 34 kgf, and they are applying a fairly generous 15% safety factor (i.e. tested ultimate strength was 224 kgf). But still, it sucks that you can't just use a normal wall plug and have to worry about this sort of thing.
That's 0.43 kN which is 430N or ~43kgf. Comparing to the rigifix table they are using a heavier aircrete and a smaller safety factor, which would take fix-v up to 80kg but that's still a big difference. I wonder if there is a testing methodology difference, as usually resin fixings are considered stronger than plug fixings.
