Question 2.
Name one mechanism of permeability.
Show hintHide hint
Consider how water moves through small spaces.
3Question 3.
What does permeability measure in concrete?
- Fluid movement

Show hintHide hint
Consider what it means for materials to allow or resist fluid passage.
4Question 4.
True or False: A higher water-cement ratio decreases permeability.
- True
- False
Show hintHide hint
Think about how the composition of concrete affects its properties.
Question 5.
A concrete sample has a water-cement ratio of 0.65 and shows significant chloride ion penetration during testing. Discuss how this impacts the durability of structures made from this concrete.
Show hintHide hint
Correlate the water-cement ratio with fluid ingress.
Question 6.
Evaluate the role of curing techniques in controlling the permeability of concrete, providing examples of various methods.
Show hintHide hint
Think about how moisture retention affects the concrete curing process.
