22.12.2. Carbonation Resistance

Try these first

1. 1.

   What is carbonation in concrete?

   Hint

   Think about the gases that can affect materials.

2. 2.

   How do polymers enhance concrete?

   Hint

   Consider what polymers provide to the concrete mix.

3. 3.

   What process leads to corrosion of steel reinforcement in concrete?

   • Frost Damage
   • Carbonation
   • Water Penetration

   Hint

   Think about the gases and their effects on materials.

4. 4.

   True or False: Polymer-Modified Concrete has no impact on carbonation resistance.

   • True
   • False

   Hint

   Remember the benefits of polymers in concrete.

5. 5.

   Evaluate a concrete structure that uses standard concrete versus Polymer-Modified Concrete for carbonation resistance. Discuss the long-term implications on safety and maintenance costs.

   Hint

   Consider the environmental conditions and material properties.

6. 6.

   Develop a maintenance plan for a structure in a high CO₂ urban area. What role would you assign to carbonation resistance provided by PMC?

   Hint

   Think about proactive versus reactive maintenance strategies.
