Question 1.
What does permeability measure?
Show hintHide hint
Think about what fluids do in relation to solids.
Question 2.
What is the Water Permeability Test (IS 3085)?
Show hintHide hint
Recall the context of testing concrete.
3Question 3.
What does the Water Permeability Test measure?
- The strength of concrete
- The depth and rate of water penetration
- The chemical composition of concrete
Show hintHide hint
Think about what this test is designed to measure.
4Question 4.
True or False: Higher permeability generally indicates better durability.
- True
- False
Show hintHide hint
Reflect on the connection between permeability and durability.
Question 5.
A new concrete mix design is proposed to reduce permeability. It involves a lower water-cement ratio and the addition of pozzolanic materials. Evaluate how these changes might influence the concrete's properties.
Show hintHide hint
Consider how these materials interact at a microscopic level.
Question 6.
Review a sample of concrete that shows signs of early deterioration. Propose a plan to assess its permeability and suggest improvements based on the findings.
Show hintHide hint
Think about different testing methods and their implications.
