2.1. Concrete Pump and RMC Transit Mixer

Try these first

1. 1.

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

   Hint

   Think about what happens if there is too much friction.

2. 2.

   What piece of equipment is used to deliver concrete from the mixer to the pump?

   Hint

   This equipment is specifically designed for transportation.

3. 3.

   What is the lubricating process used for in concrete pumping?

   • To clean the pump
   • To facilitate concrete flow
   • To cool the pump

   Hint

   Consider what helps reduce resistance in the pumping operation.

4. 4.

   True or False: RMC transit mixers can deliver concrete in a non-steady manner.

   • True
   • False

   Hint

   Think about the purpose of RMC in construction.

5. 5.

   A construction site has large aggregate sizes of 30mm being used for pumping concrete. Identify potential issues and provide solutions.

   Hint

   Refer to pipeline blockage issues discussed in class.

6. 6.

   A project manager needs to determine the appropriate slump for a concrete mix to avoid excessive cleaning efforts post pumping. What slump range should they aim for?

   Hint

   Recall the slump characteristics we discussed.
