Challenge Problems

Push your limits with challenges.

Question 1

Calculate the optimal packing density for a mix that has a combination of coarse and fine aggregates, where the aggregates in a coarse range can fill 80% of their volume. Determine how to adjust the proportions to maximize packing density.

💡 Hint: Think about measuring the volumes and their ability to fill gaps effectively.

Question 2

Evaluate how rheological properties might influence the design of a self-compacting concrete mix used for a 10-story building.

💡 Hint: Consider the effects of gravity during pouring and the need for stability in the mix.
