2.4. Test Methods

Try these first

1. 1.

   What does the Water Permeability Test measure?

   Hint

   Think about what happens to structures in wet environments.

2. 2.

   Why is chloride ion penetration considered a problem in concrete?

   Hint

   Consider the consequences of rusting.

3. 3.

   What is the purpose of the Water Permeability Test?

   • To measure fluid absorption
   • To measure moisture evaporation
   • To measure fluid penetration

   Hint

   Focus on what the test is evaluating.

4. 4.

   True or False: Chlorides enhance the strength of concrete.

   • True
   • False

   Hint

   Consider the negative effects of corrosion on strength.

5. 5.

   A concrete mix is tested for water permeability, and the results show a high permeability rate. What implications does this have for structures built with this concrete?

   Hint

   Think about how water affects concrete in various environmental conditions.

6. 6.

   A concrete structure exhibits signs of corrosion after being exposed to chlorides for years. What test could have been conducted during the mix design stage to mitigate this issue?

   Hint

   Consider preventative measures that can be implemented during design.
