I used a mixture of SDS plus with chisel and levering up and smacking
with a large sledge hammer took me about 2 or 3 days for a similar size.

Thanks everyone for the replies.

I have SDSd and couple of small areas, just to see how thick the slab
is. It was much harder work than I thought it'd be. The chisel bit
didn't manage to break the concrete, so a series of holes and cold chisel.

But I think I'll try the sledge hammer approach - I think a mate has one
I can borrow. Much as I'd like a new toy :-)

I had similar about 15 years ago. The concrete was perhaps a bit thicker and
f'ing hard! (I don't know why, as it was only a path).
Tried a 7lb one - bouncy-bouncy. Borrowed a 14 pounder and that /just/
managed.
I'm 6' 4" and I forced the hammer down as hard as I could (lifted my feet
off the ground) and kept the force on the hammer after it had hit. Typically
4 - 6 blows, naer the dge, to get it started.
I reckon somebody had installed a 30"-wide runway for a Galaxy!
