This subject covers the durability design of plain and reinforced concrete structures under various environmental loads leading to specific design life. Australian Standards require structures to be designed and built to a design life of 50 years for buildings and 100 years for infrastructure. This subject also covers the specifications and quality control measures necessary to achieve the service life by preventing durability issues during the construction phase. Students learn to understand the basic deterioration mechanisms of concrete and reinforcing steel, and to appreciate the relative importance of various control measures during the design, construction and maintenance of structures.
