Importance of Water-Cement Ratio in Concrete

Good concrete results from a good mix design and a low w/c ratio is one but very empirical part of a good mix design. Higher the water-cement ratio means the higher quantity of water which results in dilution in cement paste. It makes poor concrete mix and increases water permeability. Thus, leads to leakage and dampness.

How to Make Ultra High Performance Concrete | Hunker

Mix all ingredients for 5 minutes to blend the water. Allow the concrete to sit for 3 minutes after this initial mixing so that the water has a chance to penetrate all of the ingredients. Mix the ingredients for another 5 minutes and then you are done. You have now made ultra high performance concrete with strength of approximately 30,000 psi.
