Challenge Problems
Push your limits with challenges.
Question 1
A concrete beam is subjected to a sustained load of 100 kN. It has a water-cement ratio of 0.5 and is 10 years old. Estimate the percentage increase in strain after 5 years.
💡 Hint: Refer to typical creep coefficients based on similar concrete conditions.
Question 2
Design a concrete mix for a structure that requires minimized creep over a decade. List the key components and their roles.
💡 Hint: Think about how material properties interact to affect overall performance.
