What fireproof building materials are there?
Aerated concrete is an incombustible inorganic material. Compared with traditional building materials, its fire resistance is particularly outstanding: the fire resistance time of 1000 mm thick plate is more than 4 hours, the fire resistance time of 50mm thick plate protective steel column is more than 4 hours, the fire resistance time of 50mm thick plate protective steel beam is more than 3 hours, and the fire resistance point of1000 degrees Celsius is not less than 3 hours. Each index far exceeds the national first-class fire resistance standard.
In addition, besides hypoxia and burns, the main cause of fire victims is inhalation of toxic gases. In modern buildings, a large number of building and decoration materials will release toxic gases when burning. However, AAC board is different. Made of inorganic materials, it has no radiation, pollution and toxic gas when burning, so as to avoid personal injury in case of fire.
