Concrete Mix Ratios (Cement, Sand, Gravel)

Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard. A general rule of thumb is, if the water is palatable then it is suitable for mixing concrete.
