5.2. Curing Duration

Try these first

1. 1.

   What is curing in concrete?

   Hint

   Think about how we keep concrete hydrated.

2. 2.

   Why is the water-binder ratio important?

   Hint

   Consider how water interacts with cement.

3. 3.

   What is the recommended curing time for silica fume concrete?

   • 7 days
   • 14 days
   • 28 days

   Hint

   Think about the specifics shared in class.

4. 4.

   True or False: Curing is optional for High Performance Concrete.

   • True
   • False

   Hint

   Reflect on why we discussed the importance of curing.

5. 5.

   Given that a project requires HPC for a marine structure, detail a curing plan that meets the 14-day requirement. Include methods, timing, and resources needed.

   Hint

   Think about different environmental factors that could affect your curing plan.

6. 6.

   Critique the effects of using a water-binder ratio greater than 0.35 in HPC curing. What long-term effects could arise?

   Hint

   Reflect on how hydration affects concrete structure.
