How to Calculate Water Cement Ratio - Concrete Network

May 08, 2020  HOW TO CALCULATE WATER CEMENT RATIO. The water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a .50 water to cement ratio. If the mix lists the water in gallons ...

Water Cement Ratio Watercement Ratio Water Cement ...

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.
