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.

This more cement paste makes the concrete relatively easy to mix, place and compact as it reduces the friction between aggregates and allows its smooth movement. Thus the workability of concrete increases. When the weight of cement is less, i.e. aggregate cement ratio is more, then there will be very less cement paste to coat …

Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. The strength concrete is inversely proportional to the water/cement ratio.
