7.6.3. Fiber Reinforced High Performance Concrete

Try these first

1. 1.

   What are the benefits of incorporating fibers into concrete?

   Hint

   Think of the acronym DIC.

2. 2.

   Name one type of fiber used in FRHPC.

   Hint

   Focus on the categories of fibers.

3. 3.

   What does the term 'ductility' refer to in FRHPC?

   • Ability to absorb energy
   • Ability to deform before failure
   • Ability to resist moisture

   Hint

   Remember what happens when concrete bends.

4. 4.

   True or False: FRHPC can only utilize steel fibers.

   • True
   • False

   Hint

   Consider the types of fibers we’ve discussed.

5. 5.

   How would you design a pavement mixture using FRHPC for a high-traffic area? Consider the types of fibers and their potential impact on performance.

   Hint

   Focus on balancing between durability and flexibility needs.

6. 6.

   Evaluate the cost-effectiveness of using FRHPC in a new bridge project as opposed to conventional concrete. Consider long-term maintenance and upfront costs.

   Hint

   Think about both short-term and long-term financial impacts.
