16. Mix Design for Special Concrete Types

Try these first

1. 1.

   What is a key characteristic of Self-Compacting Concrete?

   Hint

   Think about what makes SCC special in terms of placement.

2. 2.

   What are the typical grades of High Strength Concrete?

   Hint

   Consider the requirements that define HSC.

3. 3.

   What is the main purpose of using Viscosity-Modifying Agents in SCC?

   • To increase strength
   • To enhance flow
   • To reduce cost

   Hint

   Think about the challenges SCC faces.

4. 4.

   High Strength Concrete is defined as concrete with a strength of M60 and above.

   • True
   • False

   Hint

   Recall the grades of concrete we discussed.

5. 5.

   A project requires 100 cubic meters of SCC that can flow freely in complex molds. What specific mix decisions would you recommend to ensure it meets these needs?

   Hint

   Consider both the aggregate ratio and the additives needed.

6. 6.

   In designing HSC for a high-rise building, what are the critical components you need to optimize, and what tests would you perform post-mix?

   Hint

   Recall the importance of regular testing in concrete design.
