Challenge Problems

Push your limits with challenges.

Question 1

A construction site uses a concrete mix with a water-cement ratio of 0.75. During testing, the slump is measured at 200 mm. Assess whether this is desirable for a residential application, and suggest adjustments to improve workability if necessary.

💡 Hint: Think about how high workability affects strength.

Question 2

In conditions of high ambient temperature, a concrete batch is experiencing quick slump loss. Outline steps to mitigate this issue and maintain desired workability.

💡 Hint: Consider the relation between temperature and setting time.
