Show answer and explanation

Correct answer: (D) cement soundness

The Le Chatelier test measures expansion of a cement specimen under the prescribed heating conditions. Excess expansion indicates unsound cement, commonly associated with expansive constituents such as free lime. The measured property is **soundness, D**, not strength, fineness or setting time.
