7.6. Special Types of HPC

Try these first

1. 1.

   What is SCHPC?

   Hint

   Think about what happens when concrete is poured without vibration.

2. 2.

   Name one benefit of Fiber Reinforced HPC.

   Hint

   Consider what fibers do to the structure of concrete.

3. 3.

   What unique characteristic does SCHPC have?

   • Requires vibration for compaction
   • Flows under its own weight
   • Uses coarse aggregate only

   Hint

   Remember the basics of SCHPC.

4. 4.

   True or False: RPC uses coarse aggregates for its high strength.

   • True
   • False

   Hint

   Think about what distinguishes RPC from regular concrete.

5. 5.

   Evaluate the practicality of using RPC versus conventional concrete in a bridge redesign. Discuss benefits and drawbacks.

   Hint

   Consider both performance and cost in your analysis.

6. 6.

   Examine the impact of fiber reinforcement on the design of a pavement subjected to dynamic load. What are the critical factors?

   Hint

   Think of how fibers change overall material properties.
