Durability is the ability to resist weathering action, chemical attack, and abrasion while maintaining desired engineering properties. Concrete structures require different types of durability depending on the exposure environment and desired engineering properties. Adurable material benefits the environment by conserving resources, reducing waste and the environmental impacts related to repair and replacement.
The longevity of concrete structures is readily apparent. As the most widely used building material in the world, concrete structures have withstood the test of time for many years. 
Depending on the application, the design service life of building interiors is often 30 years. However, more than double the service life. The concrete portion of structures often lasts 100 years and longer.When properly designed, concrete structures can be reused or repurposed several times in the future. Reusing concrete buildings conserves futurematerials and resources and reduces the construction time that new structures may require.
