7.2.5. Water

Try these first

1. 1.

   What type of water should be used in HPC mix?

   Hint

   Think about what kind of water is safe for consumption.

2. 2.

   Why is the water-cement ratio important?

   Hint

   Consider how too much water affects concrete.

3. 3.

   What quality must the water used in HPC meet?

   • Chlorinated
   • Potable
   • Saltwater

   Hint

   Consider what kind of water is safe to drink.

4. 4.

   True or False: A lower water-cement ratio improves the strength of concrete.

   • True
   • False

   Hint

   Reflect on the properties of concrete under different mix conditions.

5. 5.

   Analyze a case where a construction site's choice of water led to noticeable flaws in the HPC used. What methods could prevent this issue?

   Hint

   Think about the types of contaminants that can affect HPC performance.

6. 6.

   Design an experiment comparing two different water sources with varying levels of impurities on the compressive strength of HPC. Discuss your findings.

   Hint

   Examine the differences in durability and structural performance.
