Challenge Problems
Push your limits with challenges.
Question 1
A trial mix results in a slump of 20 mm when the target is 75 mm. Discuss the steps you would take to address this.
💡 Hint: Refer back to how workability is influenced in the mixing process.
Question 2
You find that the compressive strength of a concrete sample at 28 days is only 22 MPa, while your target is 30 MPa. How would you adjust your mix design?
💡 Hint: Think about how strengths can be increased through mix composition.
