Durability of Reinforced Concrete in Different ...

Sep 04, 2014  🕑 Reading time: 1 minute Durability and strength are two most important criteria for the design of reinforced concrete structures. These are the two requirements for the long term performance of concrete structures. Any deficiency in any of the two i.e. durability and strength, could make the structure unfit for the intended purpose.

What Is Durability Of Concrete? Factors Affecting It?

The durability of concrete will be affected by the shrinkage of concrete. If the cement content is exceeded, it leads to shrinkage happening in concrete. The lower cement content decreases the bondage between the concrete materials, reducing concrete strength. So using the proper amount of cement content is essential.
