Question 1.
What does XRD stand for?
Show hintHide hint
Think about the role of X-rays in material analysis.
Question 2.
What does FTIR measure?
Show hintHide hint
Consider how molecules behave when they absorb infrared light.
3Question 3.
What is the primary function of XRD?
- To measure molecular vibrations
- To identify crystalline phases
- To assess concrete strength
Show hintHide hint
Remember the purpose of X-ray diffraction.
4Question 4.
True or False: FTIR can only identify crystalline phases.
- True
- False
Show hintHide hint
Think about the broader applications of FTIR.
Question 5.
Design an experiment using XRD and FTIR for a new concrete composition intended for extreme environmental conditions. What parameters would you track, and how would analyzing the results inform your study?
Show hintHide hint
Consider what extreme conditions could affect concrete performance.
Question 6.
Evaluate a hypothetical scenario in which a concrete sample exhibits unexpectedly low durability. How could you utilize XRD and FTIR to diagnose the issue?
Show hintHide hint
Think about how each method reveals different aspects of concrete performance.
