6.3. Segregation Resistance Test

Try these first

1. 1.

   What is segregation in concrete?

   Hint

   Think about how the materials are distributed.

2. 2.

   Name one type of segregation.

   Hint

   Consider how weight affects the placement.

3. 3.

   What is segregation in concrete?

   • Separation of aggregates
   • Uniformity of mix
   • Increase in temperature

   Hint

   Think about how materials might move apart.

4. 4.

   True or False: Segregation can lead to structural failure.

   • True
   • False

   Hint

   Consider the consequences of non-uniform mixes.

5. 5.

   You are tasked with designing a concrete mix for a structural application. After testing, you found significant segregation in your sample. What steps would you take to analyze and improve the mix?

   Hint

   Consider quality control measures.

6. 6.

   If segregation occurs in your concrete during placement, what are the immediate actions you could take to mitigate this issue?

   Hint

   Think about placement practices.
