Show hintHide hint
Think about what would happen if water enters concrete.
Question 2.
Name one factor that affects permeability.
Show hintHide hint
There are several factors; consider how they change the structure.
3Question 3.
What is permeability in the context of concrete?
- Ability to hold water
- Rate at which water can pass through
- Strength of concrete
Show hintHide hint
Think about how water behaves with concrete.
4Question 4.
True or False: A higher water-cement ratio generally increases the durability of concrete.
- True
- False
Show hintHide hint
Relate this to density and fluid movement.

Show hintHide hint
Think about how each component interacts with the environment.
Question 6.
Analyze how increasing the porosity of concrete through aggregate choice affects its permeability and long-term durability.
Show hintHide hint
Consider the relationship between pores and water movement.
