Ok I am usually one for overkill but I am also not one for wasting money. I have a driveway that is 20'wide x 25' long at about 5.5 inches thick. I already installed 5/8 rebar in the entire slab. There is only at most a minivan going to be parked on the driveway. Now here is my dilemma.
This past Saturday I ordered concrete and right as the truck pulled up it started pouring. Nobody forecast rain that entire weekend. Needless to say I had to pay the 900 dollars for the 6 yards and not pour. Now I am trying to salvage a little bit of profit since I am out $900. I don't wan't to sacrifice durability though. Do I need 5000 psi or is 4000 more than enough. All opinions are appreciated
