9.8. Fire Resistance

Try these first

1. 1.

   What is the primary property that makes concrete fire-resistant?

   Hint

   Think about whether the material can catch fire.

2. 2.

   What happens to concrete when it is exposed to very high temperatures?

   Hint

   Consider what happens to moisture inside the concrete.

3. 3.

   What is the primary reason concrete is considered fire-resistant?

   • It is lightweight
   • It does not burn
   • It is a good insulator

   Hint

   Consider its basic properties.

4. 4.

   True or False: Spalling occurs in concrete when it is exposed to high temperatures.

   • True
   • False

   Hint

   Think about what high temperatures do to moisture trapped inside.

5. 5.

   Explain how the use of different types of aggregates can impact the fire resistance of concrete in a building's design.

   Hint

   Think about the fire safety standards that govern material choice.

6. 6.

   Design a concrete mix that maximizes fire resistance and state the rationale behind your choices.

   Hint

   Recall the properties of materials and their behavior under heat.
