4.2. Hardened State Properties

Try these first

1. 1.

   What is the typical compressive strength of HPC?

   Hint

   Think of the strength requirement for high-rise buildings.

2. 2.

   Name a property that HPC has lower levels of compared to conventional concrete.

   Hint

   Consider what occurs over time in a structure.

3. 3.

   What is the typical compressive strength of High Performance Concrete at 28 days?

   • 40 MPa
   • 60 MPa
   • 80 MPa

   Hint

   Think about the strength requirements for critical infrastructure.

4. 4.

   True or False: HPC has a lower modulus of elasticity compared to conventional concrete.

   • True
   • False

   Hint

   Consider how stiffness affects structural performance.

5. 5.

   Given a high-rise building designed with HPC, analyze how its hardened properties would impact its design compared to one made of conventional concrete.

   Hint

   Consider how these properties affect overall structural integrity.

6. 6.

   Evaluate how high modulus of elasticity in HPC influences its behavior under seismic loads compared to conventional concrete.

   Hint

   Reflect on how flexural capacities are vital in earthquake-prone areas.
