DURABILITY OF CONCRETE

Concrete durability has been defined by the American Concrete Institute as its resistance to weathering action, chemical attack, abrasion and other degradation processes.

Durability is the ability to last a long time without significant deterioration. A durable material helps the environment by conserving resources and reducing wastes and the environmental impacts of repair and [...]

ENVIRONMENTAL-RELATED CAUSES OF CONCRETE DURABILITY PROBLEMS
 
The inferior durability characteristics of concrete may be caused by the environment that the concrete is exposed to or by internal causes within the concrete.             
The following environmental conditions can affect the concrete durability:
 
-       Temperature
-       Moisture
-       Physical factors 
-       Chemical factors
-       Biological factors
These factors may be due to weathering conditions [...]
