14. Special Considerations

Try these first

1. 1.

   What is pumping concrete?

   Hint

   Think about what makes concrete easier to move.

2. 2.

   What does SCC stand for?

   Hint

   Recall the unique property of this concrete type.

3. 3.

   What is required for pumping concrete?

   • Higher coarse aggregate content
   • Lower coarse aggregate content
   • No change

   Hint

   Consider the flow characteristics of the concrete.

4. 4.

   True or False: Self-Compacting Concrete requires vibration to fill its form.

   • True
   • False

   Hint

   Think about the properties of SCC.

5. 5.

   Evaluate the implications of using high-performance concrete in a bridge structure. What adjustments would you need to ensure it meets safety and performance standards?

   Hint

   Consider all critical aspects, including load, environmental impact, and longevity.

6. 6.

   Suppose you are tasked with creating an SCC for a project. What are the specific requirements you would identify in your mix design?

   Hint

   Refer to SCC properties and practical adjustments based on the design.
