How to remove cement from concrete driveway?

When the fencers installed our fence, they left big chunks of cement on our driveway. Just wondering if anyone had any ideas of how to get it off with the driveway also being cement?

The attached image is one of the smaller sections left behind. (Hard to see in the image, but each of the sections is quite raised, so even just painting over wouldn’t solve the issue.)
