Researchers of Kim Chaek University of Technology developed a method of producing white magnesia cement with rocks abundant in the country as a raw material.
The economic profitability of white magnesia cement is very high as it is calcined at a low temperature and in short time. The degree of its whiteness is over 88 percent.
It can be produced by all building-material producing bases.
This method has been introduced into the Chollima Tile Factory.
