22.9. Limitations of Polymer-Modified Concrete

Try these first

1. 1.

   What is one main limitation of Polymer-Modified Concrete?

   Hint

   Consider the materials involved.

2. 2.

   Why is proper storage important for polymers?

   Hint

   Think about what happens to food if not stored correctly.

3. 3.

   What is a major limitation of PMC?

   • High bonding strength
   • Expensive Polymers
   • Quick curing time

   Hint

   Think about the materials that increase budgets.

4. 4.

   True or False: All polymers can be used interchangeably without any concerns about compatibility.

   • True
   • False

   Hint

   Consider chemical interactions in concrete.

5. 5.

   You have a project budget of $10,000. If the base concrete costs$100 per cubic meter and PMC costs $140 per cubic meter, how much PMC can you buy?

   Hint

   Use your budget to calculate how many cubic meters you can afford.

6. 6.

   Analyze the potential impact of a poorly trained worker mixing PMC. What might happen to the construction project?

   Hint

   Consider what can happen to the concrete's properties if mixed incorrectly.
