Challenge Problems

Push your limits with challenges.

Question 1

Analyze a scenario where a concrete mix has low performance. What factors among fineness, replacement level, curing conditions, and compatibility might be causing issues?

💡 Hint: Think about how each parameter interacts to influence overall concrete quality.

Question 2

If an experiment found that increasing replacement level beyond 50% diminished strength, how would you propose a balanced approach to optimize performance?

💡 Hint: Consider ranges and interactions of materials to find the sweet spot.
