Water-Cement Ratio Vs. Compressive Strength Of Concrete
2023.11.18 The water-cement ratio is a crucial factor in determining the quality and durability of concrete. A high water-cement ratio can result in poor adhesion and low tensile strength, compromising the overall strength of the concrete. On the other hand, lower water-cement ratios generally lead to stronger and more durable concrete structures.

Effect of water cement ratio. The W/c ratio is an index of the strength of concrete. The strength of cement paste increases with an increase in cement concrete and decreases with water content and air content. For the fully compacted concrete at a given age and thermal temperature, its strength is inversely proportional to the w/c ratio.
