22.6.b. Mixing

Try these first

1. 1.

   What is the first step in the mixing process of Polymer-Modified Concrete?

   Hint

   Think about what should be done before mixing.

2. 2.

   How long should you mix the concrete components?

   Hint

   Consider the typical time required for thorough mixing.

3. 3.

   What is the first step in mixing PMC?

   • Surface cleaning
   • Adding cement
   • Polymer addition

   Hint

   It's what you do before making the mix.

4. 4.

   How long should concrete be mixed for PMC?

   • True if it's 3-5 minutes
   • False otherwise

   Hint

   Consider typical mixing durations.

5. 5.

   You have a batch of PMC that appears clumpy despite mixing for 5 minutes. What should you do next? Discuss the potential causes and solutions.

   Hint

   Think about the consequences of inconsistent mixing on final properties.

6. 6.

   Explain the relationship between surface preparation and the long-term durability of PMC. How does this process affect the overall project?

   Hint

   Reflect on how initial steps impact future conditions.
