Try these first

1. 1.

   Define durability in concrete.

   Hint

   Think about how materials hold up against the elements.

2. 2.

   What does permeability measure?

   Hint

   Consider water and other liquids.

3. 3.

   What is the main factor influencing durability of concrete?

   • Water-cement ratio
   • Type of steel
   • Concrete color

   Hint

   Recall how water content affects your mix.

4. 4.

   Is carbonation harmful to concrete structures?

   • True
   • False

   Hint

   Think about what happens when CO₂ meets concrete.

5. 5.

   Given a concrete structure exposed to aggressive marine environments, outline a comprehensive mix design approach to enhance its durability.

   Hint

   Consider the specific challenges of marine exposure.

6. 6.

   Explain the role of relative humidity in the carbonation process in concrete and propose methods to mitigate its effects.

   Hint

   Think about climate control strategies for construction sites.
