11.10.4. Nano-Modified Concrete

Try these first

1. 1.

   What is nano-silica used for in concrete?

   Hint

   Think about its role in hydration.

2. 2.

   What effect do carbon nanotubes have on concrete?

   Hint

   Consider properties that allow it to withstand stress.

3. 3.

   What does nano-silica improve in concrete?

   • Porosity
   • Strength
   • Weight

   Hint

   Focus on what it’s specifically used for.

4. 4.

   True or False: Carbon nanotubes only improve the compressive strength of concrete.

   • True
   • False

   Hint

   Think about the type of strengths we discussed.

5. 5.

   Propose a design for a high-rise building in a coastal city using nano-modified concrete. What properties will you prioritize, and why?

   Hint

   Consider the specific challenges of coastal environments.

6. 6.

   Calculate the potential benefit in maintenance cost reduction over decades when using nano-modified concrete versus traditional concrete in an industrial environment.

   Hint

   Use a lifecycle cost analysis approach.
