Challenge Problems
Push your limits with challenges.
Question 1
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.
💡 Hint: Consider the requirements of a high-rise structure.
Question 2
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?
💡 Hint: Think about mixing agents and ratios.
