Concrete Mix Design | ReviewCivilPE

The strength of a concrete mix is determined by how much water versus how much cement are in it. Less water will yield a higher strength concrete. Typical values for this ratio are 57 gallons to each 94 lb sack of cement, or around 4560% by weight. Yield. Yield is the volume of concrete produced in a batch.
