That would have to depend on your version of 'decent', I would consider a nice finish, little to no visible surface cracks, able to park a 22t truck safely as being decent, your version may differ :)
A little background, for about 13 years I worked in garden supplies, 4 of those years running a yard that also had mini mix concrete.
Not all that long ago I poured 6m x 4.8m slab, * 20mpa, 150mm thick, f72 reo, 12mm reo bars, I had change left over from $600 (somewhere to park the caravan, will later widen it from 4.8m to 6m and put my workshop on it).
probably closer to $55 m2, that works out close enough to $2k for a 6x6 slab :-)Quote:
I'm sure that you'd be absolutely flat out like a lizard drinking, quoting $50/m2.
* knowing my mate, it would not surprise me if it was 25mps, heck, it could have been 32mpa
