4.3.7. Heat of Hydration Test

Try these first

1. 1.

   What does the heat of hydration refer to?

   Hint

   Think about the chemical reaction when cement meets water.

2. 2.

   What instrument is used to measure heat of hydration?

   Hint

   What do we use to analyze heat in chemistry experiments?

3. 3.

   What is the heat of hydration?

   • Heat absorbed during hydration
   • Heat released during hydration
   • No heat change during hydration

   Hint

   Consider whether the process is exothermic or endothermic.

4. 4.

   True or False: The heat of hydration is only a concern for small concrete projects.

   • True
   • False

   Hint

   Think about the scale of concrete uses.

5. 5.

   Discuss the implications of heat of hydration in constructing large bridges.

   Hint

   Think about how heat impacts setting and strength.

6. 6.

   Calculate the expected amount of heat produced in a large concrete pour if 500 kg of cement is used, given the specific heat release rate.

   Hint

   Keep the specific heat constant in the calculation for uniformity.
