I'm renovating an apt in a building built in 1960.

The floor was wood parquet glued to a 7" thick concrete slab w/rebar and large stones.

I'm wondering if the slab can be ground/sanded/buffed/sealed and work well as the finished flooring. Is there any reason structural concrete couldn't be made to look as nice as concrete made for interior residential flooring?

Here's some pics of the concrete now (it has some glue stuck to it):
