Webb21 aug. 2014 · The cement content and water content of the mix (not w/c ratio) have direct effect on the density. The water cement ratio all alone has no direct effect on the density … WebbThe 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.
