Question 1.
What is thermal conductivity?
Show hintHide hint
Consider how heat moves through materials.
Question 2.
Name one benefit of polypropylene fibers.
Show hintHide hint
Think about how these fibers react to heat.
3Question 3.
What does thermal conductivity refer to in materials?
- Ability to absorb heat
- Ability to conduct heat
- Ability to reflect heat
Show hintHide hint
Think about materials that feel hot or cold.
4Question 4.
True or False: Polypropylene fibers enhance the fire resistance of FRC by melting and creating microchannels.
- True
- False
Show hintHide hint
Consider what happens to polypropylene at high temperatures.
Question 5.
Design a fiber-reinforced concrete mix for a fire-prone area, considering the types of fibers to use based on their thermal properties. What are trade-offs?
Show hintHide hint
Consider the benefits of fiber types alongside concrete performance.
Question 6.
Evaluate how temperature fluctuations can affect the durability of FRC in different environments. What approaches can mitigate cracking?
Show hintHide hint
Think about both material and environmental factors.
