Ra Chung Yol and Cho Yong Yon, researchers from the Faculty of Resources Probing Engineering have developed white magnesia cement, green building material, from our own brucite marble, and greatly contributed to the industrialization.
Newly developed white magnesia cement can be produced in the existing process in the factory without establishing a new process and its pressure strength is42MPa.
As the burning temperature is 100~200℃ lower in comparison with dolomitecement and the range is between 400℃ and 700℃, it consumes less fuel andconvenient to produce. In particular the whiteness is over 88%, so it is far superior to another magnesia cement. Therefore, it is being used as good finishing building materials.
