22.6.d. Curing

Try these first

1. 1.

   What is curing in the context of concrete?

   Hint

   Think about what happens if concrete is not properly maintained after placement.

2. 2.

   Why might protective coverings be used for curing?

   Hint

   Consider how weather can affect new concrete.

3. 3.

   What is the primary benefit of using protective coverings during curing?

   • To speed up the setting process
   • To prevent moisture loss
   • To enhance strength immediately

   Hint

   Think about what could happen to concrete in extreme weather.

4. 4.

   True or False: Polymer-modified concrete typically requires extensive moist curing.

   • True
   • False

   Hint

   Consider the role polymers play in curing.

5. 5.

   Given a scenario where PMC is placed during a hot summer day, describe the potential curing challenges and the appropriate preventive strategies.

   Hint

   Consider how weather affects hydration levels.

6. 6.

   If a construction site has limited resources for moist curing, how could polymer-modified concrete's properties alleviate the need for such resources?

   Hint

   Think about the role of polymers and their properties.
