Question 1.
Define workability in concrete.
Show hintHide hint
Think about what makes it easy to handle concrete.
Question 2.
What is the water-cement ratio?
Show hintHide hint
It’s an important numerical relationship in mixing concrete.
3Question 3.
What does higher workability in concrete typically lead to?
- Higher strength
- Increased water content
- Reduced flowability
Show hintHide hint
Think about how we make concrete easier to work with.
4Question 4.
True or False: Lower workability guarantees higher strength in concrete.
- True
- False
Show hintHide hint
Consider risks like segregation.
Question 5.
A construction firm must decide between two concrete mixes. Mix A has high workability but low compressive strength, while Mix B has low workability but high strength. Discuss the implications of choosing each mix in regards to a high-rise building construction.
Show hintHide hint
Consider the requirements of a high-rise structure.
Question 6.
During a project review, an engineer notes frequent segregation in their concrete mix due to high workability. What steps can they take to remedy this while keeping the concrete usable?
Show hintHide hint
Think about mixing agents and ratios.
