The building-materials technology research institute under Pyongyang University of Transport has solved technical problems arising in the moulding and production of hard plaque with light burned magnesia.
The plaque consists of materials with strong durability and resistance to fire and water, which absorbs carbon dioxide and, in particular, is free from distortion.
The plaque was inscribed as a cutting-edge technology product as it is thin and has fine physio-dynamic properties and good colours and patterns. It is widely used in the interior wall finishing of dwelling houses and public buildings and furniture production instead of plastic and wood boards.
The institute has also developed a method of producing newel posts, terrazzo and other building parts with light burned magnesia.
