22.6.c. Placing and Finishing

Try these first

1. 1.

   What does SSD stand for in the context of surface preparation?

   Hint

   Think about the state of the surface when it's ready for concrete.

2. 2.

   Why is it essential to mix PMC for at least 3–5 minutes?

   Hint

   Consider what happens when components are not mixed well.

3. 3.

   What does SSD stand for when preparing surfaces for PMC?

   • Strong Surface Density
   • Saturated Surface Dry
   • Standard Surface Dry

   Hint

   Focus on the saturation level of the surface.

4. 4.

   True or False: Moist curing is generally necessary when using Polymer-Modified Concrete.

   • True
   • False

   Hint

   Think about the role of the polymer in the curing process.

5. 5.

   Consider a project where the ambient temperature is very high during PMC placement. What special measures should be taken to ensure good bonding and finishing?

   Hint

   Think about how heat affects curing and surface conditions.

6. 6.

   Draft a detailed protocol for the placement of PMC that includes considerations for surface preparation, mixing, finishing, and curing.

   Hint

   Consider each step's objective and the considerations for best practices.
