In the home, marble is generally used in places with relatively large space, such as villas, single buildings, and levitation floors. The walls must have a certain load bearing capacity. Because marble itself is heavy, when it is used in large areas, it is necessary to consider the wall. The load-bearing nature of floors and floors is mainly used for the background wall of televisions when they are partially decorated, and also has the effect of sound insulation.
The key to choosing marble is to distinguish A, B, and C stone types. The building materials industry standard “JC518-93 Control Standards for Classification of Radioactive Protection of Natural Stone Products†jointly formulated by the National Building Materials Bureau and the Ministry of Health stipulates that Class A radioactivity is relatively small and its scope of use is not limited; Class B should not be used for indoor living Decoration can be used in other places; Class C can only be used for exterior decoration of buildings. In general, the radioactivity of dark marble is relatively high. According to tests, the radioactivity of different colors of stone is also different, the highest is red and green, and the lowest is white and black.
