- 1.
What does permeability refer to?
Hint
Think about how water moves through a sponge.
- 2.
Why is a lower water-to-cement ratio beneficial?
Hint
Consider strength in concrete.
- 3.
What is the effect of a lower water-to-cement ratio on permeability?
- Increases permeability
- Decreases permeability
- No effect
Hint
Consider how density affects movement.
- 4.
True or False: Higher porosity generally means lower permeability.
- True
- False
Hint
Think about how much space is available for water.
- 5.
You have two concrete samples: one with a w/c ratio of 0.55 and another with 0.35. Predict which one will have higher permeability and why.
Hint
Consider how water affects the concrete mixture.
- 6.
