1.3. Measurement of Workability

Try these first

1. 1.

   What does workability in concrete refer to?

   Hint

   Think about mixing and placing concrete.

2. 2.

   What is measured in a slump test?

   Hint

   What happens when concrete is placed?

3. 3.

   What does the slump test measure?

   • a) Flowability
   • b) Vertical settlement
   • c) Compaction

   Hint

   Focus on what happens to the concrete when it’s poured.

4. 4.

   The Compacting Factor Test is used to measure:

   • True
   • False

   Hint

   Think about compacting the concrete.

5. 5.

   Design a concrete mix for a high-rise building where workability is critical. Discuss how you would choose the tests to ensure the mix is appropriate.

   Hint

   Consider the importance of reaching every spot in a tall structure.

6. 6.

   A construction team experiences challenges with concrete setting too quickly during summer. Propose a solution incorporating tests mentioned to manage workability.

   Hint

   Think about temperature's effect on the concrete.
