4.1. Slump Flow

Try these first

1. 1.

   What is the target slump flow range for Self-Compacting Concrete?

   Hint

   Consider why we need a specific measurement.

2. 2.

   What does slump flow measure?

   Hint

   Think about its self-compacting properties.

3. 3.

   What is the typical slump flow range for SCC?

   • 300 mm - 400 mm
   • 650 mm - 800 mm
   • 900 mm - 1000 mm

   Hint

   Remember the ideal values we've discussed.

4. 4.

   True or False: Self-Compacting Concrete needs mechanical vibration to perform well.

   • True
   • False

   Hint

   Recall the definition of Self-Compacting Concrete.

5. 5.

   A construction team finds that their slump flow consistently measures below 650 mm. Discuss potential causes and how they could troubleshoot this issue.

   Hint

   Review the factors that influence slump flow to identify the root cause.

6. 6.

   Calculate the potential impact of poor slump flow on a large high-rise project. How might it affect the overall schedule and costs?

   Hint

   Think about how disruptions in work processes can accrue costs and time.
