The practical range of water-cement ratio ranges from 0.3 to 0.8, which gives weak and stiff concrete, respectively. Weak concrete means a fairly wet concrete. Compressive strength of about 5600 psi can be obtained in the concrete of the water-cement ratio 0.4. This value will go down to 2000 psi when a water-cement ratio of 0.8 is used.

What is Water Cement Ratio? Its Calculation [Complete Guide]
For the calculation of water quantity for concrete, first of all, we have to find the quantity of cement. Just assume that the required volume of cement for the mix is 100 kg and W/C is 0.4. Water Quantity = Water-Cement Ratio x Volume of Cement. Water Quantity = 0.4 x 100 kg = 40 liters / 100 kg cement or (20 liters / 50 kg cement bag).
