Water-cement ratio in concrete mix design affects the strength, durability, workability, and permeability of the concrete.
Water-cement ratio determines the amount of water needed to fully hydrate the cement in the concrete mix.
A lower water-cement ratio leads to higher strength and durability of the concrete.
An excessive water-cement ratio can result in lower strength, increased permeability, and reduced durabilit...
