Without seeing the beam details it would be hard to answer. With no beams or changes in elevation you are needing 55 to 60 cubic yards.

It would weaken the concrete, so keep out the salt.
I'm sure it depends upon how well you prepare the subsurface. A good foot of hardpack, quality dirt with another six inches to a foot of roadbase underneath four inches of properly laid concrete can offer some major load bearing qualities. If I were you, I would research how the Autobahn and similar roads are constructed. They are built very differently from most highways and Interstates in the United States.
I think you are talking about embedding steel rods (rebars) in concrete, right? This would make the concrete much stronger. It is called reinforced concrete, and you can make all sorts of structures with it, something that you can't do with ordinary concrete. Though, I am not even sure anyone is using non-reinforced concrete nowadays.
That would depend on the wire thickness, and size of mesh.
Assuming a thickness of four inches, there would be a total of 139 (138.89) cubic yards of concrete.
1 cubic yard covers 324 square feet per inch of thickness, divide 324 by thickness in inches to get coverage, i.e. 4 inches thick would cover 324/4=81 square feet, 36 inches thick would cover (you guessed it) 9 square feet.
5 inches or greater. Reinforced, of course.
Spread it evenly, then leave your hands in the cement for 4-6 hours to spread excess cement.
Assuming a thickness of four inches and allowing about 5% waste, you would need 9.33 cubic yards or about 419 80lb bags.
Well assuming the depth of concrete is going to be 1 meter you will need 846 cubic meters of concrete.
any thickness of concrete can be poured however if it contains an aggregate you would be limited to the diameter of the stone. you may also replace the water component with a latex additive that will substantially improve the strength.
It is all dependant on how thick the concrete is. You take the square footage and turn that into cubed feet (where the thickness comes in) if its 1" thick you multiply the square footage by.083, if its 2" thick you multiply by.17. To come up with this number you take the thickness say 3" and divide that by 12 (12 inches in a foot), so for 3 inches you get .25. So back to the question at hand, say your 30 square feet of concrete is 6 inches thick, your equation would look like this: 30 X .5 = 15. So 15 is your cubed footage. You then multiply this number by 150 which is the weight in pounds of 1 cubic foot of concrete. The number you come up with is 2,250. That is the amount in pounds of your 30 square feet of concrete assuming it is 6 inches thick.
Depends on the thickness of the paper. Measure the thickness in decimals of an inch and multiply that by 40.
Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch
870; a quarter has a thickness of about 0.07 inches, and 61 / 0.07 = 870.
You would typically use inches to measure a paperback book. You can measure the length, width, and thickness of the book in inches to determine its size.
