Try these first

1. 1.

   What is meant by nano-modified concrete?

   Hint

   Think about what Nano indicates in materials.

2. 2.

   Why is reduced permeability important?

   Hint

   Consider how water affects concrete.

3. 3.

   What do nanoparticles do in nano-modified concrete?

   • Increase weight
   • Enhance hydration
   • Make it less durable

   Hint

   Think about what's critical for concrete curing.

4. 4.

   True or False: Nano-modified concrete has a higher permeability than regular concrete.

   • True
   • False

   Hint

   Remember what makes concrete vulnerable.

5. 5.

   Consider a new waterfront development project. Discuss how the use of nano-modified concrete would benefit the long-term durability of the structures.

   Hint

   Think about environmental exposure factors.

6. 6.

   You are tasked with evaluating the cost-benefit of using nano-modified concrete for a bridge project. Explain the factors you would consider in your analysis.

   Hint

   Consider both upfront and ongoing costs.
