7.4.1. Define Requirements

Try these first

1. 1.

   What is the characteristic compressive strength required for most High Performance Concrete applications?

   Hint

   Think about standard concrete strength expectations.

2. 2.

   Why is it important to assess exposure conditions when designing HPC?

   Hint

   Consider weather or environmental stresses.

3. 3.

   What is the characteristic compressive strength (fck) that HPC typically exceeds?

   • 40 MPa
   • 60 MPa
   • 80 MPa

   Hint

   Recall the strength levels discussed.

4. 4.

   Durability requirements need to consider which environmental condition?

   • True
   • False

   Hint

   Think about the resilience against environmental stresses.

5. 5.

   Given a project in a marine environment where chloride attack is a concern, outline the requirements for the HPC mix, including compressive strength, workability, and selected materials.

   Hint

   Think about material performance in exposure conditions.

6. 6.

   Describe how to balance the need for high strength and workability in a high-performance concrete mix designed for extreme climate conditions, considering durability as well.

   Hint

   Reflect on admixtures that impact both workability and durability simultaneously.
