Challenge Problems

Push your limits with challenges.

Question 1

A construction firm has soil with varying moisture content. They initially added 3% cement and found it insufficient after tests. Describe the adjustments they should make based on our study.

💡 Hint: Evaluate how moisture impacts soil strength.

Question 2

If the Standard Proctor test shows a higher density than expected with 4% cement, what could that indicate, and what should be the next steps?

💡 Hint: Consider how the density correlates with moisture levels.
