Challenge Problems
Push your limits with advanced challenges
Design a testing plan for a new concrete mix. Specify the necessary specimens, testing methods, and what properties you aim to evaluate.
💡 Hint: Consider which properties are crucial for your intended application.
Given a cylindrical specimen with a diameter of 150 mm and a length of 300 mm, if the maximum load at failure was recorded as 300 kN, calculate the tensile strength.
💡 Hint: Make sure to convert kN to N for the calculations.
