[Shop-talk] Concrete cure time

[eric at megageek.com]

quick question, what is the cure time for concrete before you can drill 
and put expansion anchors in it?

I poured two small pads last week and I want to mount the buoys on them, 
but I don't know how long i should wait.  Some sources tell me 72 hours, 
some say 7 days, and other say 28 days.

This isn't structural or anything, just a level pad to hold buoys.

Any ideas?  TIA
