7.5.1.b. Fiber-Reinforced Concrete

Try these first

1. 1.

   What is Fiber-Reinforced Concrete?

   Hint

   Think about what materials can enhance concrete.

2. 2.

   Name one type of fiber used in FRC.

   Hint

   What materials can be used to strengthen concrete?

3. 3.

   What does fiber-reinforced concrete help improve?

   • Workability
   • Strength
   • Durability
   • All of the above

   Hint

   Think about overall benefits of adding fibers.

4. 4.

   True or False: Fiber addition always reduces concrete workability.

   • True
   • False

   Hint

   Reflect on how fibers might interact with concrete.

5. 5.

   Propose a construction scenario where fiber-reinforced concrete would be advantageous. Discuss the specific type of fibers you would use and why.

   Hint

   Consider locations exposed to high traffic.

6. 6.

   If given a low-fidelity concrete mix that is prone to cracking, describe how you would modify the mix using fibers.

   Hint

   Think about what kinds of fibers work well in flexible scenarios.
