watercement (w/c) ratio. It really is as simple as it sounds. Just take the weight of water in a cubic yard and divide it by the weight of cement. Durable concrete mixes usually need a w/c ratio of .50 or less (lower is better). So, to translate, that would mean a mix with 500 lbs of cement shouldn't have more than 250 pounds of water
