Try these first

1. 1.

   What does HPC stand for?

   Hint

   What is a term that describes superior quality concrete?

2. 2.

   Name one common SCM.

   Hint

   Think of materials that improve concrete's properties.

3. 3.

   What is the primary benefit of using supplementary cementitious materials (SCMs) in HPC?

   • Increase workability
   • Reduce shrinkage
   • Improve strength and durability

   Hint

   What do these materials add to the concrete mix?

4. 4.

   True or False: All types of aggregates can be used without considering their grading.

   • True
   • False

   Hint

   What term describes the arrangement of different sized aggregates?

5. 5.

   Evaluate the impact of using low-quality aggregates in HPC. What effects can this have on the overall performance?

   Hint

   Consider what properties aggregates contribute to concrete.

6. 6.

   Propose a mix design strategy that incorporates multiple SCMs for optimal performance in HPC. What are the advantages of this approach?

   Hint

   Think about what each material brings to the table.
