Question 1
What is the typical range for the water-cement (w/c) ratio in most applications?
- 0.1 to 0.2
- 0.4 to 0.6
- 0.8 to 1.0
💡 Hint: Think about the balance between strength and workability.
Question 2

Challenge Problems
Push your limits with challenges.
Question 1
Develop a hypothetical scenario requiring a high strength concrete mix. Determine the appropriate w/c ratio and justify your choice based on project requirements.
💡 Hint: Consider structural requirements versus allowable workability.
Question 2
A construction project shows failing compressive tests on concrete with a w/c ratio of 0.7. What steps would you recommend to rectify the issue?
💡 Hint: Think about how you can improve strength while maintaining workability.
