Answers: Buy a bag of the cheapest kitty litter you can find...you don't have need of the fancy kind that kill odors, etc.
Dump the bag of kitty litter on the grease spots and leave it here for several days. The kitty litter will absorb the grease.
It really works. You may still have a slight stain, but nought like what is in attendance now.
Good luck!
Farm Implement Paint reducer will remove the grease from the surface but due to the porous nature of cement, some grease will be impossible (as far as I know) to remove.
