Question 1

What does fineness testing indicate about a mineral admixture?

  • It determines the color of the admixture.
  • It measures the reactivity and blending efficiency.
  • It indicates the time of setting in concrete.

💡 Hint: Think about what makes fine particles useful in a mix.

Question 2

True or False: A higher Pozzolanic Activity Index means lower strength gain in concrete mixes.

  • True
  • False

💡 Hint: Recall how we measure the effects of pokzolanic materials.

Challenge Problems

Push your limits with challenges.

Question 1

You need to design a concrete mix that minimizes the effects of high water absorption in fly ash. Discuss how you would utilize specific tests before finalizing your mix design.

💡 Hint: Think about benefits from specific properties of the admixture.

Question 2

Evaluate the appropriateness of using high-loss-on-ignition fly ash for a marine structure exposed to aggressive environments. What actions would you recommend?

💡 Hint: Refer to implications of LOI on long-term durability.
