Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula to calculate the curvature coefficient?
- C_c = (D30^2) / (D10 * D60)
- C_c = (D10^2) + (D30 * D60)
- C_c = (D60 - D30)/D10
💡 Hint: Look for the formula that uses squared and multiplied terms.
Question 2
True or False: A curvature coefficient less than 1 indicates a well-graded soil.
- True
- False
💡 Hint: Remember what grading characteristics indicate.

Question 1
A soil sample shows D10 = 0.15 mm, D30 = 0.45 mm, and D60 = 0.95 mm. Calculate the curvature coefficient and interpret its significance.
💡 Hint: Make sure to pay attention to the values given as they lead to the calculation.
Question 2
Discuss the relevance of particle size distribution in the context of a construction project. Provide examples of how different grading can impact engineering decisions.
💡 Hint: Think about how soil interacts with structures.
