The water-cement ratio affects both the strength and durability of cement mortar.
Its essential to understand the chemistry of the problem. Go for a technical sheet available online.
Good question.
Interesting question. In general, the higher the water cement ratio, the lower of strength and many durability properties. However, each property may have its optimum w/c.
Very useful and interesting discussion, thanks to all.
Interesting discussion !
According to the literature w/c of 0.5 is a suitable to achieve a good strength a good durability
