Try these first

1. 1.

   What is the main purpose of lubrication in concrete pumping?

   Hint

   Remember the term 'Lubricate to Flow'.

2. 2.

   What size should aggregates not exceed for pumpable concrete?

   Hint

   Think about the maximum size limits.

3. 3.

   What is the first step before concrete pumping?

   • Cleaning the pump
   • Lubricating the pump
   • Setting up the boom

   Hint

   It helps prevent clogs.

4. 4.

   True or False: The maximum size of aggregate in pumpable concrete should be over 25 mm.

   • True
   • False

   Hint

   Remember the guidelines for effective pumping.

5. 5.

   Devise a concrete mix design for pumping in a congested urban site, delineating the specifications and how each element will aid in pumpability.

   Hint

   Think about urban constraints and how concrete properties interact.

6. 6.

   Analyze a scenario where a concrete pipeline experiences clogging despite proper lubrication. What could be the cause and how would you address this issue?

   Hint

   Consider all elements that affect flow.
