Challenge Problems
Push your limits with advanced challenges
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.
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.
