Discussion
Consider the following statements about finish grinding.
1. Gypsum is interground with the clinker.
2. Mill temperature must be kept below the dehydration point of gypsum.
3. Fineness has no effect on the water demand of the cement.
Answer: B
The first two are correct. The third is wrong, since a greater surface area requires more water to wet it, and water demand rises with fineness alongside early strength. Both effects follow from the same increase in surface area.
