Try these first

1. 1.

   What is the benefit of using supplementary cementitious materials?

   Hint

   Think about how they help the environment.

2. 2.

   Name one type of recycled aggregate.

   Hint

   Consider where we get these materials from.

3. 3.

   What is one benefit of using recycled aggregates?

   • Increases natural resource consumption
   • Reduces waste
   • Lowers concrete durability

   Hint

   Think about the environmental benefits.

4. 4.

   True or False: Using low-carbon cements does not affect concrete strength.

   • True
   • False

   Hint

   Consider how alternatives can be beneficial.

5. 5.

   Propose a concrete mix design incorporating SCMs and recycled aggregates to meet a specific strength requirement.

   Hint

   Consider how each component contributes to strength.

6. 6.

   Critically assess the potential risks associated with using recycled aggregates in high-strength concrete applications.

   Hint

   What aspects of reliability need to be assessed?
