Question 1.
What does permeability in concrete refer to?
Show hintHide hint
Think about how water interacts with concrete.
Question 2.
Name the two main types of permeability tests mentioned.
Show hintHide hint
Consider tests that involve fluid flow.
3Question 3.
What is the primary purpose of permeability testing?
- To determine compressive strength
- To assess durability against fluid ingress
- To check workability
Show hintHide hint
Think about the effects of water on concrete.
4Question 4.
True or False: The RCPT measures the water content in concrete.
- True
- False
Show hintHide hint
Recall the specific metrics the RCPT evaluates.
Question 5.
You are testing a new concrete mix intended for a marine structure. The RCPT indicates a high chloride ion penetration rate. What steps would you take to modify the mix to improve durability?
Show hintHide hint
Focus on the mix components that affect permeability.
Question 6.
Critically analyze how environmental factors during curing affect the permeability of concrete. Provide examples.
Show hintHide hint
Think about the curing conditions you might observe.
