I'd leave it alone. But if you want to change, I'd get a diamond cup grinder and grind away at the paint on the block edges. You might need to wash it with a muriatic acid to help with adhesion. Or maybe there might be a product to act as a primer to help with the bonding do a Google search.. Then I'd apply cement on the seems with a trowel. I'm just a gerry rigger but I think this should work fine. run it by a concreate pro. Probably paint it in a couple of days so it doesn't dry to fast.
