If you use the broken blocks, I would make fair size piles. At least a couple feet high. In my opinion, better to make fewer piles with the same amount of rock or broken blocks than very small piles or worse scattering them single over the bottom of the pond. I put some smaller stuff in my pond that is already mostly covered with FA or sediment. The larger piles will stay viable longer and thereby be more useful.
An example would be a three foot diameter pile a couple foot high minimum. If you have lots of the broken blocks, five or six feet in diameter and three feet high would be even better.
I'm not an expert, but it is what I would do with broken blocks. The small fish and critters will love the holes and hiding places it makes. Small fish and critters concentrated attracts the biger fish.
