Challenge Problems

Push your limits with challenges.

Question 1

A construction project requires a water-cement ratio of 0.5. If 200 kg of cement are used, how much water is required if the moisture content of the aggregate is known to be 10%? Calculate adjusting the water as necessary based on the moisture content.

💡 Hint: Remember to adjust the water quantity for the moisture already present in the aggregates.

Question 2

During a lab test, a sample weighs 150g in its wet state and weighs 140g after drying. Calculate the moisture content and discuss its implications for a concrete mix design.

💡 Hint: Use the moisture content formula to calculate correctly.
