Concreate Durability

• A structure would be considered as durable if it fulfilled its intended duty for the whole of its design life with the least maintenance .
• All materials deteriorate : this is not a defects but rather an inherent characteristic
• The total deterioration of a material can be expressed as a functrion of the environment , design , workmanship , material properties & its use .
• Concrete has the potential of an almost unlimited life , unless it is subjected to chemical attack by an aggresive environment or suffers some physical damage .
