It doesn't look at all like what you would industrial concrete expect to look like.
On top of that, I personally prefer a hard border between hazard and non hazard concrete. It enables me to clearly mark hazard areas.

Like some of the images posted earlier in this thread I'd expect them to be sharp borders.
The texture used for the concrete would however work well as a precursor to concrete if it's used as a regular stone floor. (a cheaper alternative so to speak)
