2.3. Segregation Resistance

Try these first

1. 1.

   What is segregation resistance?

   Hint

   Think about how SCC performs under its own weight.

2. 2.

   Name one test used to assess segregation resistance.

   Hint

   It measures flow time through a funnel.

3. 3.

   What is the primary purpose of segregation resistance in SCC?

   • To enhance workability
   • To prevent component separation
   • To improve aesthetics

   Hint

   Think about why segregation might be problematic.

4. 4.

   Is the V-Funnel test used to evaluate segregation resistance?

   • True
   • False

   Hint

   Consider what aspects the test is measuring.

5. 5.

   Analyze a case where poor segregation resistance led to failure in a concrete structure.

   Hint

   Consider the importance of proper mix design in maintaining strength.

6. 6.

   Design an SCC mix focusing on maximizing segregation resistance for a high-rise building project.

   Hint

   What must you balance in your design to ensure both flow and stability?
