Question 1.
What is the typical compressive strength required for HPC?
Show hintHide hint
Consider the strength criteria for structural elements.
Question 2.
Why is slump important for concrete?
Show hintHide hint
Think about how the concrete will be mixed and placed.
3Question 3.
What is the typical compressive strength range for High Performance Concrete?
- 20-40 MPa

4Question 4.
True or False: The slump of concrete impacts its setting time.
- True
- False
Show hintHide hint
Think about how easier placement might change initial hardening times.
Question 5.
Consider a situation where the compressive strength for a bridge is set below 60 MPa. Discuss potential consequences.
Show hintHide hint
Think about the stresses a bridge must endure.
Question 6.
If the slump of concrete is too high, how could this lead to problems during setting?
Show hintHide hint
Consider how too much water affects concrete cohesion.
