As I referred to, there are various mixes of concrete. The most common is somewhere between 2400 psi and 3000 psi. It's been 30+ years since I poured and finished the stuff, so I'm not quite sure. There are additives you can put in concrete to accelerate the 28 day cure time. The concrete used in pre fab work is much stronger and cures faster than what you would use in a sidewalk or patio. Putting heavy equipment on a green slab will crack the thing. ( slab that is) The site foreman will tell them when they can set up their equipment. The contractor will give the green light. There are many types of concrete, please compare apples to apples, not apples to potatoes. This was just for FYI , I realize things may not move as fast as we would like, I was just trying to cast some light on the situation. Also they have equipment that reads hardness and moisture. Just saying.
