Another "old rule of thumb" for mixing concrete is 1 cement : 2 sand : 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable. This mixture may need to be modified depending on the aggregate used to provide a concrete of the right workability. The mix should not be too stiff or too sloppy.
Mixing. Mix in a wheelbarrow or on a pre-wet surface using clean, drinkable water wherever possible. Use a maximum of 5 litres. Too much water will result in a weaker concrete. Empty contents of inner cement bag and mix thoroughly with sand and stone. Gradually add water and mix to an even consistency.
