Discussion
Assertion (A): Some plants grind clinker and slag separately and blend them afterwards.
Reason (R): The two materials differ in hardness and have different optimum finenesses.
Answer: D
Correct answer: Both A and R are true, and R is the correct explanation of A
Both are true and the reason gives the mechanism. Slag is harder than clinker and reacts more slowly, so it wants to be ground finer, not coarser. Intergrinding gives the opposite result. Grinding each to its own optimum and blending afterwards costs an extra mill and gives a better product.
