5. Properties of Hardened SCC

Try these first

1. 1.

   What is compressive strength?

   Hint

   Think about how concrete is tested for its strength.

2. 2.

   Why is durability important in construction?

   Hint

   Consider environmental factors and wear over time.

3. 3.

   What does compressive strength indicate?

   • The resistance of concrete to tension
   • The maximum load concrete can withstand
   • The proportion of materials in concrete

   Hint

   Think about what happens when a heavy load is applied to concrete.

4. 4.

   True or False: SCC has higher durability due to its lower permeability.

   • True
   • False

   Hint

   Consider how permeability affects long-term concrete strength.

5. 5.

   You are tasked with assessing the overall performance of a high-rise building constructed with SCC. Discuss how the properties of hardened SCC contribute to its structural integrity and longevity.

   Hint

   Think critically about each property and its real-life applications.

6. 6.

   Propose a mix design adjustment for hardened SCC that balances strength and durability. Justify your choice.

   Hint

   Consider the impact of each component in the SCC mix.
