Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
