During the manufacturing process of cement the temperature of the decomposition zone goes upto:
Correct answer: B. 800°C
- A. 600°C
- B. 800°C
- C. 1000°C
- D. 1200°C
Explanation
800°C is the correct temperature range for the decomposition zone in cement manufacturing. At this temperature, raw materials such as limestone undergo calcination, where they decompose into lime (calcium oxide) and carbon dioxide.
