Try these first

1. 1.

   What is the purpose of optimizing particle packing in HPC?

   Hint

   Think about the overall performance benefits.

2. 2.

   Name a commonly used fine material for particle packing optimization.

   Hint

   This material is a byproduct and enhances strength.

3. 3.

   What is the main goal of particle packing optimization?

   • Increase workability
   • Reduce porosity
   • Add color

   Hint

   Consider the relationship between density and performance.

4. 4.

   True or False: Using more coarse aggregate always decreases permeability.

   • True
   • False

   Hint

   Think about the concept of voids.

5. 5.
