Look up concrete in Wikipedia for detailed information.
Concrete for a foundation or floor is generally mixed in the proportion 1 part cement, 2 parts sand, and 4 parts gravel (or crushed stone). Crushed stone is better than water worn stone as its irregular shape makes for stronger concrete.
If a bag of cement is approximately 1 cu. ft., a 1:2:4 mixture calls requires 1 bag cement, 2 cu. ft. sand and 4 cu. ft. stone
Since the sand and cement fills the voids of the stone the above quantities yield 4½ cu. ft. concrete.
The concrete mixture is mixed, by hand with a shovel or in a portable powered concrete mixer, with water just sufficient to provide a workable mixture for the work in hand. Care is needed not to use too much water as this weakens the final concrete.
