Challenge Problems
Push your limits with challenges.
Question 1
You are tasked with designing a concrete mix for a project but your initial test shows a slump of only 25mm when 100mm is ideal. Discuss possible adjustments and their implications.
💡 Hint: Be mindful of the water-cement ratio in your adjustments.
Question 2
During compressive strength testing, if you unexpectedly find a cube failing at 20 MPa while the target is 30 MPa, what might be the causes, and how would you address them?
💡 Hint: Think about common issues in material selection or mixing.
