The compressive strength of concrete is generally measured

Question

Quizplus · Accepted Answer

The compressive strength of concrete is generally measured after 28 days of casting the concrete in a test specimen because this is the time required for the concrete to attain its maximum strength. Testing the concrete before or after 28 days may not give accurate results as the concrete may not have attained its maximum strength. Therefore, option E (28 days after casting the concrete in a test specimen) is the best choice.
