1.4. Best Practices in Pumping

Try these first

1. 1.

   What is the primary purpose of lubrication in concrete pumping?

   Hint

   Think about how oil helps a machine operate smoothly.

2. 2.

   What size must aggregates be limited to when pumping concrete?

   Hint

   Think about how big objects can block a flow.

3. 3.

   What is the primary role of lubrication in concrete pumping?

   • To speed up the pumping
   • To reduce friction during flow
   • To cool down the pump

   Hint

   Why do engines need oil?

4. 4.

   True or False: A rubber plug is necessary during the cleaning process to clear blockages in the pipeline.

   • True
   • False

   Hint

   Think of what happens when you try to clear a straw with a plug.

5. 5.

   A construction site has limited space and requires mobility for concrete placement. Which types of pumping methods would best fit this scenario and why?

   Hint

   Think about transportation in congested areas.

6. 6.

   Discuss why it is critical to maintain a specific aggregate size in concrete designed for pumping. What impact does exceeding this size have?

   Hint

   Think about how large items can block smaller openings.
