Cold concrete meets warm moist air = sweating floor.
What is the real question: is the floor slick and hard to walk on? Do you track water into the house?
You would likly need to warm the floor to really eliminate the sweating. A thin coating of say epoxy will not stop the sweating. If you build a raised wooden floor you may trap moisture under the flooring resulting in mold.
If you are thinking about indoor outdoor carpet I suggest you get a square yard sample and lay it on the floor for a few days to see if it cuts down on the thermal transfer. At the end of the test look under the carpet to see how much moisture has accumilated there.
In the end is it really worth the effort of trying to solve?
