12.1. Extended Service Life

Try these first

1. 1.

   What does the term 'service life' refer to in construction?

   Hint

   Think about how long a building typically lasts.

2. 2.

   Name one benefit of High Performance Concrete.

   Hint

   Consider how frequently repairs would be needed with HPC.

3. 3.

   What does HPC stand for?

   • High Performance Concrete
   • High Pressure Concrete
   • High Polymer Concrete

   Hint

   Focus on the purpose of the concrete.

4. 4.

   True or False: HPC has a lower service life compared to conventional concrete.

   • True
   • False

   Hint

   Think about the longevity properties discussed.

5. 5.

   Given a structure designed with HPC, calculate the expected service life difference if it were built with conventional concrete. Consider factors like permeability and strength.

   Hint

   Reflect on the properties affecting durability and costs.

6. 6.

   Discuss how the introduction of supplementary cementitious materials could transform the sustainability aspect of Highway construction. What metrics determine success?

   Hint

   Relate this to standard construction practices.
