Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What indicates that an aggregate is classified as flaky?
- Thickness < 0.6 × mean size
- Length > 1.8 × mean size
- Thickness > mean size
💡 Hint: Think about how thickness relates to the standard of 0.6.
Question 2
True or False: Elongated aggregates are desirable in concrete mix.
- True
- False
💡 Hint: Recall what elongation means in the context of shape.

Challenge Problems
Push your limits with challenges.
Question 1
Given a sample aggregate with 30% flaky particles and 50% elongated particles, discuss the potential impacts on a concrete mix's performance.
💡 Hint: Visualize how these shapes interlock when mixed.
Question 2
Design an experiment to compare the performance of concrete made with standard aggregates versus those with high flakiness and elongation indices.
💡 Hint: Think about variables you might need to control in your mixes.
