Heat is a bad thing for concrete curing. You want it to be cold, because the curing process is exothermal - it creates its own heat. Keep it as cold and wet as you can. I've seen large pours where they replace the water with ice, just to keep the temperature down.
When I was doing civil engineering work, we used to have to have observers onsite during the summer when concrete was being placed, just to make sure the contractors were keeping the concrete wet and cool. They'd ignore it as soon as you turned your back and then when the customer called and said it cracked months later, they'd want proof no one drive a semi over it.
Thanks Fred, I'm aware. Not much I can do while sleeping. It's being wetted regularly for the first week.
Edit: while sleeping, I could have purchased/rented curing blankets and put them on, but I didn't. It's not really flatwork, and it's effectively insulated on 5 of the 6 sides, so I think it'll be fine.
