Challenge Problems

Push your limits with challenges.

Question 1

You have two types of aggregates for a concrete mix: Aggregate A has a specific gravity of 2.5, and Aggregate B has a specific gravity of 3.0. If you need a mix that utilizes both while optimizing mix strength, how would you choose the proportions?

💡 Hint: Reflect on how specific gravity relates to strength.

Question 2

A project requires concrete with a specific gravity close to 2.7. You have aggregates with specific gravities of 2.3, 2.4, 2.6, and 2.9. How would you proceed to create the required concrete mix?

💡 Hint: Think about how mixing aggregates impacts the outcome.
