Typically, a batch of concrete can be made by using 1 part Portland cement, 2 parts dry sand, 3 parts dry stone, 1/2 part water. The parts are in terms of weight not volume. For example, 1 cubic foot ( m 3 ) of concrete would be made using 22 lb (10.0 kg) cement, 10 lb (4.5 kg) water, 41 lb (19 kg) dry sand, 70 lb (32 kg) dry stone (1

If I remember correctly, 1:2:4 concrete ran 2500 psi for the higher slumps and up to 3500 psi for the low to medium slumps. Just to keep everyone shaking their heads, My father & I used that proportion to place some in fill slabs around the house in 1968, kept the slump low and had 4000 psi concrete.
