Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with constructing a high-rise building that requires concrete to surround very dense reinforcements effectively. Describe the importance of improved workability and the potential consequences if it is not achieved.

💡 Hint: Think about what happens when there’s not enough fluidity in a concrete mix.

Question 2

You have been asked to evaluate two concrete mixes: one with high superplasticizer content and one with low. What predictions can you make about their workability and potential uses in construction?

💡 Hint: Consider how superplasticizers change the dynamics of a concrete mix.
