Discussion
Consider the following statements about cement testing.
1. Standard consistency is determined before setting time.
2. The Le Chatelier test measures soundness.
3. Loss on ignition measures the fineness of the cement.
Answer: B
The first two are correct. The third confuses two quite separate tests, since loss on ignition indicates pre-hydration and carbonation while fineness is measured by air permeability or sieving. Each test has its own apparatus and answers its own question.
