Which of the following processes is used for the synthesis of cement ?
Correct answer: C. both
- A. dry process
- B. wet process
- C. both
- D. none
Explanation
Cement can be manufactured by either the dry process, in which dry raw materials are ground and fed to the kiln, or the wet process, in which they are made into a slurry with water. Both processes produce clinker that is ground with gypsum to make cement. Choosing only one process ignores the other established manufacturing route.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
