Question 1.
What is the bond strength that PMC typically achieves with old concrete?
Show hintHide hint
Think about the units of pressure.
Question 2.
Why is surface preparation important for bonding?
Show hintHide hint
Consider how better surfaces help materials stick together.
3Question 3.
What is the bond strength achieved by PMC with old concrete?
- Less than 1 MPa
- 1.5 - 2 MPa
- Greater than 1.5 MPa
- 2.5 MPa
Show hintHide hint
Consider the performance characteristics of PMC.
4Question 4.
True or False: Surface preparation does not affect bond strength.
- True
- False
Show hintHide hint
Think about the steps needed before applying concrete.
Question 5.
In a real construction project, PMC was applied without proper surface preparation. Analyze the potential consequences of this oversight in terms of bond strength and long-term structural integrity.
Show hintHide hint
Reflect on consequences and consider the relationship between preparation and performance.
Question 6.
Evaluate the impact of using different types of polymers in PMC on bond strength with existing concrete. Discuss potential trade-offs in various applications.
Show hintHide hint
Think about the implications of material choices in engineering.
