6.10. Case Studies of Water-Related Failures

Try these first

1. 1.

   What was the main issue in the RCC building case?

   Hint

   Think about the types of water used in construction.

2. 2.

   What is a key factor for proper concrete setting?

   Hint

   Consider the role of different types of water.

3. 3.

   What caused the corrosion in the RCC building case?

   • A) Low pH water
   • B) High chloride levels in sea water
   • C) Organic contamination

   Hint

   Think about the nature of the water used.

4. 4.

   True or False: Organic contamination can lead to delayed setting times.

   • True
   • False

   Hint

   Consider the types of materials that affect hydration.

5. 5.

   Analyze a scenario where construction is performed near a river. Outline a testing protocol for the water used from this river to ensure its quality meets construction standards, considering potential contaminants.

   Hint

   Think about the impurities we discussed in class.

6. 6.

   Suppose a construction project reports delayed setting times. Develop a plan for investigating the cause including tests to run.

   Hint

   Consider both internal and external factors affecting performance.
