hi
You could mess around in maya for hours trying to get that same texture. I have no doupt it can be done, by using either noise, ramps or fractial nodes. If i was going to do something like that, i would be looking around for some high res, photos of cement. Change the photo to greyscale, then invert it. Save it out as a bump map.
Then in maya, you could use the orginal cement photo for your colour, and then add the bump map that you just made. With some good lighting it would look as good as that photo.
If you are going to have it cover a large area, you would need to make it tileable in photoshop or some other compisition proggy.

Also you could use a displacement map, added with the bump map. That would add some realism, but also you would need to have a fairly high tessellation on the plane.

just some suggestions.. Peace!
