I'm starting my 3 bay tractor shed/barn this weekend. This is bare bones sort of thing with a metal shed roof, open sides, dirt floor and I'm trying to do it on the cheap. But, it looks like I might have a little extra cash in the budget and it sure would be nice to have concrete floors.

I know nothing about concrete. And my first problem is figuring out how much I need and how much it will cost and I don't even know how to estimate. If I can figure that out, and if I can afford it, then I'll figure out how.

The floor area will be 34' x 20'. It will need to support my tractor and implements but I have no idea how thick it needs to be. Based on that, can anyone tell me how much I'll need?

How many cement trucks full is that?
How much does a truck full cost?

If I decide to mix and pour my own, how many bags, gravel and or sand do I need?

If all this looks too expensive I might just do the center bay which is where I'll park my tractor. It will be 12' x 20'.

If anyone can help me out with this it would be very much appreciated. As for the how, I'll ask those questions later but I will have access to help/supervision from someone who has done this before.

Thanks.
