Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a concrete mix design calling for a 0.5 water-to-cement ratio, if your aggregates retain a moisture content of 3%, how should you adjust your mix?

💡 Hint: Consider what it means for the final ratios.

Challenge 2 Hard

If concrete experienced significant cracking and spalling after a year, hypothesize how moisture adjustments could have prevented it.

💡 Hint: Reflect on the relationship between moisture and strength over time.
