Assertion (A): Coloured cement is normally based on white cement rather than grey.
Reason (R): The grey background would dull and shift any pigment added to it.
Answer: C
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. Grey clinker owes its colour to iron compounds, and that grey shows through any pigment added, muting it and shifting the hue. White cement is made from low-iron raw materials at greater cost, and the pigment then gives the colour it was chosen for.
