~ 1 cu. ft.
Limestone is refined to make portland cement.
3 cubic feet or about one-tenth of a cubic yard. Cement is generally quantified in yards or cubic yards. It takes 27 cubic feet (3x3x3) to make a cubic yard. Therefore 3 cubic feet is about .111 or about one-tenth of a cubic yard (3 divided by 27).
A 15' x 20' x 4" slab needs at least 3.7 cubic yards.
No you can NOT(from my research)

Yes. The cement used to make concrete usually has sand, aggregate and Portland cement in it. That would make it heterogeneous.
5 or 6. An 80 lb. bag of ready mix concrete will make about 1/2 cubic foot of concrete. A 94 lb. bag of portland cement mixed with 1 1/2 cu. ft of stone (coarse gravel) and 1 cu. ft. of sand will make 3 cubic feet of concrete or 6 times as much. (this is a common 1:2:3 mix) Quikcrete ready mix is often made with 1 part cement, and 2 1/2 parts each sand and stone. A 1:1 1/2: 3 mix is a stronger mix but you get less volume, at 5 1/2 cubic feet per bag of cement.

I think so ........
Mortar is made from sand, a cement such as Portland Cement or Lime, and water.
Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
27 cubic feet in a cubic yard, so 5 cubic yards is equal to 135 cubic feet
