I have a back concrete patio in pretty good shape. Surrounding it on 2 sides are concrete pads (| is one pad and the other is -). These two pads are about 1 foot a piece wide. The X's are the brick pillars.

So I demo'ed brick and moved electric. Now I am left with about a 1 inch base that seems pretty attached to concrete where the pillars where - they were about 1 foot by 1 foot. This 1" base looks like a smooth concrete - it isn't mortar and is definitely different from the rough/normal concrete pad. And there is a rebar anchor sticking out the middle hole. Any ideas beyond demoing these two large concrete pads? Do I have a chance of taking out these small (smooth) concrete pillar bottoms and flattening these things out? And I am guess that I just hit the rebar with angle grinder and fill the middle if I can get the pillar bottoms out?
