13.3. Factors Affecting Pumpability

Try these first

1. 1.

   What does the term 'pumpability' refer to?

   Hint

   Think about the transport process.

2. 2.

   What shape of aggregate is generally better for pumpability?

   Hint

   Consider how shapes interact during movement.

3. 3.

   What effect does an angular aggregate have on pumpability?

   • Improves pumpability
   • Reduces pumpability
   • No effect

   Hint

   Remember the shape's impact on movement.

4. 4.

   True or False: A high water-cement ratio will always improve pumpability.

   • True
   • False

   Hint

   Consider the balance between water and cement.

5. 5.

   You’re tasked with designing a pumping operation for a construction site with restricted access. What factors will you consider to ensure pumpability?

   Hint

   Consider all factors we've discussed around the pumping process.

6. 6.

   Analyze the potential consequences of using a very low water-cement ratio while pumping concrete with angular aggregates.

   Hint

   Think through each aspect of how the components interact.
