3 cards from this section. Quick, good the night before a test.
What does w/c ratio stand for?
Think about what the ratio measures related to concrete.
What is the typical range of a water-cement ratio recommended for concrete?
You've learned about the balance between strength and durability!
What is the typical range for the water-cement (w/c) ratio in most applications?
Think about the balance between strength and workability.
True or False: A lower water-cement ratio usually results in higher strength.
Recall how water content affects concrete density.
Develop a hypothetical scenario requiring a high strength concrete mix. Determine the appropriate w/c ratio and justify your choice based on project requirements.
Consider structural requirements versus allowable workability.
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?
Think about how you can improve strength while maintaining workability.
