Question 1

What does effective size (D10) indicate?

  • Size at which 10% of soil is finer
  • Size at which 50% of soil is finer
  • Size at which 100% of soil is finer

💡 Hint: Remember the number associated with D10.

Question 2

A uniform soil has a uniformity coefficient (Cu) less than 3. True or False?

  • True
  • False

💡 Hint: Consider what qualities a well-graded soil would have compared to a uniform soil.

Challenge Problems

Push your limits with challenges.

Question 1

Scenario: A soil sample has a D10 of 0.15 mm, D30 of 0.25 mm, and D60 of 0.45 mm. Calculate the uniformity coefficient (Cu) and classify the soil's grading.

💡 Hint: Remember the formula for uniformity coefficient is Cu = D60/D10.

Question 2

Case Study: You are tasked with designing a foundation for a structure in a region with 90% silt. Predict how this uniform soil behavior might affect the construction.

💡 Hint: Consider how silt behaves under load and its water retention capabilities.
