Q: What kind of cement is employed in the manufacture of artificial marble?
  • A. High Alumina cement
  • B. Air Entraining cement
  • C. Hydrographic cement
  • D. White cement
Correct Answer: Option D - Artificial marble–Artificial marble can be either pre-cast cast in-sites. These are made from Portland gypsum cement and sand. In the pre-cast variety, the cast stone is removed after three days. On the fifth day of casting these are treated with a solution, liquid fluorite of magnesia. It is then washed and warped in paper 24 hours and then once again treated with the liquid. After one month the stone is polished by rubbing energy over the surface with a linen rag ball dipped in mixture of lime water and silicate of potash and then the process is repeated energy. It is used for external works. • White cement is employed in the manufacture of artificial marble.
