Challenge Problems
Push your limits with advanced challenges
A batch of concrete tested under a controlled environment yielded a maximum load of 800 kN with a cube measurement of 300 mm x 300 mm. Calculate the compressive strength and discuss what influences would affect this result.
💡 Hint: Ensure to convert kN into N to use this in the formula.
In a compressive strength test, samples yield varying results. One shows 30 MPa, another 25 MPa. Discuss how erroneous curing could lead to such discrepancies.
💡 Hint: Consider how hydration dynamics might vary across different specimens.
