14. Durability Maintenance and Retrofitting

Try these first

1. 1.

   What is the main purpose of durability maintenance?

   Hint

   Think about what happens when maintenance is neglected.

2. 2.

   Name one retrofitting technique used for concrete structures.

   Hint

   Consider methods that protect the surface of concrete.

3. 3.

   What is the purpose of retrofitting techniques?

   • To improve the rigidity of structures
   • To enhance the longevity of existing structures
   • To replace damaged concrete

   Hint

   Think about ways to make old structures more durable.

4. 4.

   True or False: Predictive maintenance involves using technology to predict when repairs are necessary.

   • True
   • False

   Hint

   Consider the role of sensors in maintenance.

5. 5.

   A city is experiencing accelerated deterioration of its concrete bridges due to chloride exposure. Propose a comprehensive retrofitting strategy and include at least two techniques that should be implemented.

   Hint

   Think about how exposure conditions influence the choice of methods.

6. 6.

   Discuss the potential impacts of failing to implement predictive maintenance systems in critical infrastructure. Suggest alternative methods for monitoring.

   Hint

   Consider the trade-offs between technology and traditional methods.
