Challenge Problems
Push your limits with advanced challenges
Given a concrete mix design using 100 kg of recycled aggregates with a water absorption of 10%, how would you adjust the water content to maintain workability?
💡 Hint: Consider how much water the aggregates would absorb and add that into your equation for the overall water needed.
Evaluate how using a higher proportion of rough recycled aggregates could affect the overall concrete performance and suggest ways to counter these effects.
💡 Hint: Think about how to balance texture and paste in your mix design.
