Concrete at least it will bite easier than a poilshed surface.
Have you got a hand trolley you can slip the squares onto for moving them off ?
Most are rated at 250kg.
Lots of water on the blades will cool the diamond cutting tip down so they should keep reasonably sharp but I would say 200m into blocks will take 3-4.
