Question 1.
What is the purpose of a slump test?
Show hintHide hint
Think about the consistency of concrete.
Question 2.
What does compressive strength measure?
Show hintHide hint
Consider what happens under pressure.
3Question 3.
What is the primary purpose of the slump test?
- To measure compressive strength
- To evaluate workability
- To assess thermal properties
Show hintHide hint
Think about what might happen to the concrete during placement.
4Question 4.
True or False: High Performance Concrete relies solely on mixing without further testing.
- True
- False
Show hintHide hint
Consider what is necessary to validate the performance of concrete.
Question 5.
Design an experiment to test the effectiveness of different superplasticizers on HPC workability. Include your testing methods.
Show hintHide hint
Consider how each additive would change the fluidity of the concrete.
Question 6.
How would you address a situation where HPC tested below the expected compressive strength? Outline steps to investigate and solve.
Show hintHide hint
Think about the components of your mix and the procedures followed.
