Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If you have a concrete mix of 12 m³ and you aim to use coarse aggregates at 45%, how much volume of coarse aggregates will you require?

💡 Hint: Multiply the mix volume by the proportion you're targeting.

Challenge 2 Hard

Design a concrete mix considering that less than 10% of coarse aggregate could lead to a failed mix. Given a total volume of 15 m³, what’s the minimum volume of coarse aggregate needed?

💡 Hint: Calculate 10% of the total volume to find the minimum needed.
