5.3. Radius of Influence and Amplitude Frequency

Try these first

1. 1.

   What is the purpose of the lubricating process in concrete pumping?

   Hint

   Think about what makes things flow better.

2. 2.

   What do we use to clean the pump after the pouring process?

   Hint

   It's a device used to remove blockages.

3. 3.

   What is the ideal maximum size of aggregates for pumpable concrete?

   • 10 mm
   • 20 mm
   • 25 mm
   • 30 mm

   Hint

   Think about the size ratio to the pipe.

4. 4.

   True or False: It is recommended to use aluminum pipes when pumping concrete.

   • True
   • False

   Hint

   Look for reactions with construction materials.

5. 5.

   A construction company plans to use a concrete pump on a site with heavily reinforced columns. Describe the concrete mix design they should implement, detailing every aspect based on provided guidelines.

   Hint

   Think about how reinforcement impacts the aggregate size choice.

6. 6.

   Evaluate a scenario where a team used aluminum pipes to pump concrete. Discuss the potential repercussions they might face and suggest appropriate materials they should rather consider.

   Hint

   Remember to consider the properties of the materials in chemical reactions.
