I did our extension on the side of our driveway in 1998 doing 5" of concrete and 1/2" rebar at 20" square.

On one area the concrete had a dark look and has flaked in that area. I cured it as good as can be done. No idea what was the reason.

Surface spalls on wet finished surfaces (slabs) is caused primarily by a few things or combinations of them.
Too much water used as a finishing aid.
Freeze thaw cycling (exaggerated by ^)
Chlorides deteriorating the surface. (Salt/de icers)
Has very little to do with curing methods.
If the concrete is new(er), it was likely too much water during floating or troweling.
