Sunnyside, WA
Poured 6" thick, no rebar on the end of silage pit. Waited 7 days then drove the 28,000 lb payloader on it. Just poured 80 more yards added to it and will be driving loaded tmr wagons on it after 7 days. Tractor and tmr weigh ~90,000 loaded
The longer you wait, the better. Concrete will crack. It has to. If you saw joints, it just limits the crack to mainly where the joints are located.
