I've replaced a raised patio, The new patio overhangs the original base by 20 cm so it wouldn't be a good idea to stand right at the edge of it until I shore it up with something. Would aerated concrete blocks (and mortar) suffice?
I'm drawn to them because I assume they will be easy to cut?
The 100mm "lite" 3.6kN blocks support 15 tonnes each

grrrr ... it got stuck sending and I thought I'd waited long enough to see if it arrived

Thanks, should support me comfortably then!
And yes, they are easy to cut - I did a fair number of them for my conservatory, with an old, worn out, circular saw blade; a few more with a hand-saw; and channelled for cabling and cut-out for back boxes, using an old router bit!
But are they frost proof ?. I doubt it.
Why? Why not use ordinary medium density ones, or (better) bricks? When you get a decent frost, your aerated blocks will turn to s-.
But as for the underlying base that is what you need to be looking at. Brian
To be fair, the OP wanted a temporary support pending something more permanent.
Fairly thick concrete laid about 20 yrs ago so should be fine.
