   What is nanotechnology?

   Hint

   Think about materials on a very small scale.

2. 2.

   Define self-healing concrete.

   Hint

   What happens when a crack forms in this type of concrete?

3. 3.

   What is the primary benefit of nanotechnology in concrete?

   • Increased weight
   • Reduced permeability
   • Improved color

   Hint

   Think about which option relates to durability.
