What is High Performance Concrete?
Show hintHide hint
Think about what makes it different from regular concrete.
Question 2.
Name one material used in HPC.
Show hintHide hint
These materials enhance the performance of concrete.
3Question 3.
What is the typical compressive strength of HPC?
- 30 MPa
- 60 MPa
- 100 MPa
Show hintHide hint
Look for the specified range in the section.
4Question 4.
True or False: HPC has a higher permeability than conventional concrete.
- True
- False
Show hintHide hint
Remember how HPC is formulated to resist environmental factors.
Question 5.
Assuming you're tasked to design a HPC mix with a target compressive strength of 80 MPa. Outline your steps to determine the appropriate materials and proportions for the mix.
Show hintHide hint
Think sequentially about the mixture design process.
Question 6.
You have been asked to evaluate the durability of a concrete sample containing 15% fly ash and 10% silica fume. Discuss how its resistance to chloride penetration might be better compared to a sample with 25% regular cement.
