I can assure you that concrete does set, The only movement you'll find in any concrete slab, is from expansion and contraction. As the whole section of slab will expand and contract at the same rate, the only damage to any cable, would be where it enters or exits that section of slab. That's why we have flexible /sliding joints in conduit/trunking/tray-work etc, across concrete slab expansion joints!!! Concrete does take a fair old time to reach it's full strength though, 70ish years so i'm told!! lol!!!
