Water cement ratio and its effect on strength and durability of concrete?

Question

Accepted Answer

Water cement ratio affects the strength and durability of concrete by influencing the workability, porosity, and permeability.

Lower water cement ratio leads to higher strength and durability due to reduced porosity and permeability.
Higher water cement ratio can decrease strength and durability as it increases porosity and permeability.
Optimum water cement ratio is crucial for achieving desired concrete properties.
Excessive water can lead to segregation and bleeding in concrete mix.
Example: A water cement ratio of 0.4 is commonly used for high strength concrete.
Example: A water cement ratio of 0.6 may be suitable for easy placement in certain applications.
