Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with evaluating two aggregates for a construction project. Aggregate A has a specific gravity of 2.5 and water absorption of 3%, while Aggregate B has a specific gravity of 2.8 and water absorption of 1.8%. Which aggregate would you recommend and why?

💡 Hint: Evaluate the implications of each aggregate’s properties.

Question 2

Design a scenario where you might encounter issues due to high levels of water absorption in the aggregates used during a rainy season on-site. Discuss the potential consequences.

💡 Hint: Consider how aggregates interact with water during various weather conditions.
