What is the Right Water-Cement Ratio for Mix Design?
For high-quality concrete construction, a lower water-cement ratio of 0.4 is employed. For concrete construction like driveways and sidewalks, a w/c ratio ranging from 0.6 to 0.7 is normally used. The practical range of water-cement ratio ranges from 0.3 to 0.8 that gives stiff and weak concrete respectively.

Water-Cement Ratio and Concrete Strength: Formula
The practical best water-cement ratio is from about 0.40 to over 0.60. A ratio of 0.3 is made concrete too stiff (unless superplasticizers are used). A ratio of 0.8 makes concrete wet and fairly weak concrete. Normal compressive strengths when concrete is properly cured are: 0.4 w/c ratio –> 5600 psi. 0.8 w/c ratio –> 2000 psi.
