Challenge Problems
Push your limits with challenges.
Question 1
A batch of aggregate weighs 2400 kg and fills 1.2 m³. Calculate the bulk density and discuss its implications for concrete mix design.
💡 Hint: Use the density formula and think about how density affects overall strength.
Question 2
In an aggregate mix, the void content is tested to be 25%. If the total volume of the mix is 9 m³, how much volume of paste will be needed?
💡 Hint: Consider the role of voids in determining how much paste is required.
