1.1. Factors Influencing Durability

Try these first

1. 1.

   What is the definition of durability?

   Hint

   Think about how long materials last under different conditions.

2. 2.

   Name one environmental factor influencing durability.

   Hint

   Consider what types of weather or substances can harm concrete.

3. 3.

   What does durability ensure in construction materials?

   • It prevents cracking
   • It maintains engineering properties
   • It improves aesthetic

   Hint

   Focus on what durability is meant to accomplish.

4. 4.

   True or False: Water-cement ratio affects only the workability of concrete.

   • True
   • False

   Hint

   Consider all the properties affected by this ratio.

5. 5.

   Evaluate the durability of concrete used in a coastal bridge exposed to seawater and suggest modifications to enhance its performance.

   Hint

   Consider the environmental factors that affect durability and how they can be mitigated.

6. 6.

   Design a basic plan to combat freeze-thaw deterioration in concrete structures.

   Hint

   Think about what can be added to concrete mixes and construction techniques that resist weather impacts.
