9.20.2. Thermogravimetric Analysis (TGA)

Try these first

1. 1.

   What does TGA stand for?

   Hint

   Think about the process involving temperature and weight.

2. 2.

   Why is TGA important for concrete?

   Hint

   Focus on hydration and durability aspects.

3. 3.

   What does TGA measure in materials?

   • Mass change with temperature
   • Volume change with pressure
   • Color change with heat

   Hint

   Think about the relationship between temperature and material properties.

4. 4.

   True or False: Thermogravimetric Analysis provides insights into only the thermal properties of cement.

   • True
   • False

   Hint

   Consider the broader applications of this analysis.

5. 5.

   Explain how TGA would differ in analyzing a standard concrete mix compared to a high-performance mix. What results would you expect?

   Hint

   Consider the impact of mix design on hydration efficiency.

6. 6.

   How would you use TGA results to optimize a concrete mix to enhance its fire resistance?

   Hint

   Focus on hydration products associated with thermal stability.
