Challenge Problems
Push your limits with advanced challenges
You are given two concrete mixes: one with a normal water-cement ratio and one with water-reducing admixtures. Discuss the expected differences in workability and hydration time between the two.
💡 Hint: Consider both the chemical interactions and physical properties.
Design a hypothetical case study for a large-scale construction project requiring pumped concrete. Discuss how you would utilize water-reducing admixtures and justify your choices.
💡 Hint: Reflect on the practical considerations that influence mix design.
