Durability of Concrete Types of Durability and Factors

Durability is defined as the capability of concrete to resist weathering action, chemical attack and abrasion while maintaining its desired engineering properties. It normally refers to the duration or life span of troublefree performance. Different concretes require different degrees of durability depending on the exposure environment and properties desired.
