3. 3.

   What is one advantage of using steel fibers in FRC?

   • High tensile strength
   • Low cost
   • Biodegradable

   Hint

   Consider what property is commonly associated with metals.

4. 4.

   True or False: Glass fibers can be used without treatment in high-alkali environments.

   • True
   • False

   Hint

   Think about the durability issues discussed.

5. 5.

   Design a concrete mix for an industrial floor where high tensile strength is required. Which fibers would you include and why?

   Hint

   Think about the requirements for flooring in industrial settings.

6. 6.

   Evaluate the trade-offs of using natural fibers versus synthetic fibers in terms of cost, performance, and durability.

   Hint

   Consider both the environment and the engineering demands.
