7.3. Marine Durability: Jetty Structure in Coastal Gujarat

Try these first

1. 1.

   What is marine durability?

   Hint

   Consider where these structures are typically found.

2. 2.

   Name one cause of corrosion in marine jetties.

   Hint

   Think about environmental factors affecting these structures.

3. 3.

   What is one of the main causes of corrosion in a jetty structure?

   • Inadequate cover
   • Low water-cement ratio
   • Poor air-entrainment

   Hint

   Think about how rebar is protected.

4. 4.

   True or False: High-performance concrete is less permeable than standard concrete.

   • True
   • False

   Hint

   Consider the structural categories.

5. 5.

   Evaluate the potential consequences of inadequate cover over rebar in a coastal jetty design. What mitigation strategies would you propose?

   Hint

   Consider examples of other durable designs.

6. 6.

   Design a durability enhancement plan for a new jetty intended for heavy marine exposure. What materials and methods would you choose to ensure longevity?

   Hint

   Draw upon the knowledge of materials discussed in class.
