7.9.A. Transportation and Handling

Try these first

1. 1.

   What is the ideal delay time between mixing and placing HPC?

   Hint

   Think about workability.

2. 2.

   What truck is preferred for transporting HPC?

   Hint

   It helps keep the mix unseparated.

3. 3.

   What is the maximum ideal time between mixing and placement of HPC?

   • 60 minutes
   • 120 minutes
   • 30 minutes

   Hint

   Recall our discussion about timing.

4. 4.

   True or False: Self-Compacting Concrete should be vigorously vibrated during placement.

   • True
   • False

   Hint

   Consider the special handling requirements.

5. 5.

   Evaluate the impact of neglecting proper transportation methods on the overall performance of HPC in a high-stress environment.

   Hint

   Think about the integrity of the concrete over time.

6. 6.

   Formulate a comprehensive plan for curing HPC during a particularly hot day, considering both materials and methods.

   Hint

   Consider both the chemical and physical aspects of curing.
