Challenge Problems
Push your limits with advanced challenges
A concrete mixture uses 500 kg of cement. If 30% of this is replaced with GGBS, calculate how much GGBS is used. Discuss the implications of this replacement on hydration heat.
💡 Hint: Apply percentage calculations.
Predict how the permeability of concrete could change when 20% of the cement is replaced with a highly reactive pozzolan compared to normal cement hydration.
💡 Hint: Consider the properties of C-S-H versus Ca(OH)₂.
