This will have to support tractor traffic and some school buses and heavy trucks. What should I specify for base, thickness, reinforcement, mix, expansion joints etc. I want concrete not asphalt. Thanks Phil If your getting this done for free, go pay a local engineer to give you specs. NOBODY on here knows your soil type, texture, permeability, and if your soil is expansive or not. Good concrete starts with a good base. Grade and drainage are important as well and again, no one here can see that. You have one chance to do it right make the most of it.

I'm with '36F30' the only thing I would add is to use fiber in the mix if you want strength; and it is much cheaper than rebar. Fiber is kind of a new technology in the concrete world (last 10 or 15 years or so) They clam that is is stronger than steal and it does give a lot of strength to concrete. I drove concrete trucks for over 10 years and worked with concrete for over 20 years. I found the fiber (now micro-fiber) is so inexpensive I used it in footers, grout and mortar mixes. Now if I think concrete I think fiber, but I also still use rebar and/or wire.

I would try to refrain from using any calcium because it diminishes the tinsel strength considerably. As for air entrainment I would ask the dispatcher how much to use. They will know the idiosyncrasies of the mix and the area, like water and soil pH and what they are using No. 1 or No.2 cement, and what type of cement they are using (Portland). This can change the amount of air entrainment you will need or if you need to use it at all. When your are mixing 4 1/2 oz. to 8 yards of mix a 1/2 oz. can make or break ya (don't excuse the pun). Air entrainment makes micro bubbles in the mix which expands the amount of mix but after a certain point the concrete becomes soft.

Also think of the future... are you going to bring any tracked rigs inside the shop on the slab? If you think you might I would put rail road rails (steal) in the slab where the tracks will travel. Leaving the rails slightly exposed so the tracks wont destroy the slab.
