Hey,
There is nothing special about this material, following the basic rules the corona's youtube tutorial below should suffice for that.
The Floor barely looks like concrete to me ^^
Glossy reflection with fresnel and a bump texture should take care of how light interacts with the floor. The main problem will be finding the bump and diffuse textures. Maybe you can find a polished wood texture and recolor it brown and recolor the bright / dark places in photoshop, since it looks an aweful lot like a polished piano, with a bumpy surface.
Either way, you don't give much to work with.
First of all, confirm that it is indeed the floor, and that you need help creating the
material, not the texture.
Also provide how far you came so far / max file with your current concrete material on a plane or just the whole scene, if your contract allows it. Somebody will look at it and correct it to match what you need help with.
Otherwise all you get will be Hit and miss ultra generic text replies... like this one :D
