2020-9-1  Water Cement ratio is the relative weight of water to that of cement in the concrete mixture. It is also denoted by W/C ration. In Concrete, the water-cement ratio determines the final properties of the concrete. The Water-cement ratio is the most important factor behind the strength of concrete.

2021-11-15  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.
