Try these first

1. 1.

   What do we mean by hydrophobic in relation to cement?

   Hint

   Think about water and its interaction with materials.

2. 2.

   Name one additive used in hydrophobic cement.

   Hint

   What would help repel water?

3. 3.

   What does hydrophobic mean?

   • Water-absorbing
   • Water-repelling
   • Neutral

   Hint

   Think about water interactions.

4. 4.

   True or False: Hydrophobic cement is ideal for long-term storage.

   • True
   • False

   Hint

   Consider cement storage conditions.

5. 5.

   Design a hypothetical experiment to compare the moisture absorption rates of regular cement versus hydrophobic cement.

   Hint

   Focus on the importance of controlled variables.

6. 6.

   Assess the potential economic impact of using hydrophobic cement in a region with high rainfall compared to traditional cement.

   Hint

   Think about maintenance costs under different conditions.
