Question 1.
What does the term 'pumpability' refer to?
Show hintHide hint
Think about the transport process.
Question 2.
What shape of aggregate is generally better for pumpability?
Show hintHide hint
Consider how shapes interact during movement.
3Question 3.
What effect does an angular aggregate have on pumpability?
- Improves pumpability
- Reduces pumpability
- No effect
Show hintHide hint
Remember the shape's impact on movement.
4Question 4.
True or False: A high water-cement ratio will always improve pumpability.
- True
- False
Show hintHide hint
Consider the balance between water and cement.
Question 5.
You’re tasked with designing a pumping operation for a construction site with restricted access. What factors will you consider to ensure pumpability?
Show hintHide hint
Consider all factors we've discussed around the pumping process.
Question 6.
Analyze the potential consequences of using a very low water-cement ratio while pumping concrete with angular aggregates.
Show hintHide hint
Think through each aspect of how the components interact.
