Discussion
Assertion (A): A coarse raw meal tends to leave free lime in the clinker.
Reason (R): Larger silica particles do not combine completely with the lime during burning.
Answer: B
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. Lime combines with silica by solid-state diffusion, and a large quartz grain cannot be reached to its centre in the time and temperature the kiln provides. The lime it should have taken up remains as free lime, which is why free lime in the clinker is read as evidence about the meal as well as about the burning.
