A ratio by weight of 0.5 water, 1 cement, 3 sand, and 3 gravel should make a fine concrete, although a little less water (0.4 by weight) would make stronger concrete. The same by volume ( ie. buckets) is a good ratio as well, 1/2 to 1 to 3 to 3 (or a little less water- too much water weakens the concrete, and there will always be some water ...

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.

The cement content of concrete is of less significance than the w/c ratio for structural durability, provided the mix is of adequate workability. The cement content for a hydropower structure is normally between 220 and 375 kg m −3. Concrete mix design is decided by two factors: strength and durability.
