Question 1.
What is the typical range of cement used in PMC mix designs?
Show hintHide hint
Think about the standard quantity of cement used in construction.
Question 2.
What is the desirable range for water-to-cement ratio in PMC?
Show hintHide hint
Consider how adding too much water affects the concrete.
3Question 3.
What is the appropriate percentage of polymer in a PMC mix?
- 5%
- 10-20%
- 50%
Show hintHide hint
Reflect on the section discussing polymer dosage.
4Question 4.
True or False: A higher water-to-cement ratio always leads to better concrete.
- True
- False
Show hintHide hint
Think about the roles of water and cement in strength.
Question 5.
A contractor wants to create a mix for a waterproofing membrane using PMC. They need a total volume of 5 m³. If using 400 kg/m³ cement and maintaining a water-to-cement ratio of 0.4, calculate the amount of polymer, water, fine aggregates, and coarse aggregates needed.
