In temps above freezing, your concrete will reach full design strength in 14-21 days (approximately). But what is that? Did you pour 3000 PSI or 4000 PSI or...? Within 7 days, it will reach 50-75% design strength. So let’s say 1500 PSI (pounds per square inch). Your rig weighs...? Your tires take up how many square inches of space? If you had 1 tire only and it took up 24 square inches, the concrete below it could withstand 36,000 pounds of static pressure (@ 1500 PSI).
No wood. It’s a barn, who cares about staining. We leave ours plugged in 24/7/365 and the fridge stays on the whole time. Done this with 3 campers...NO problem.
That's not how it works when considering the strength that will not crack.
Some do care about appearance and the guy with a new floor just might be able to head off staining that cannot be reversed.
Well, actually it kinda is. We regularly begin erection of large heavy objects on new concrete that are no more than 7 days cured. If weather and conditions are accommodating, we may even begin in 3 days. Nary a problem.
