日本的加气混凝土制作技术,是从瑞典引进的。从1963年开始生产以来一种兼有轻质、耐火、隔热保温等性能的预制板材已迅速得到普及。它用于从住宅到超高层建筑的各种建筑物的屋面、楼板、外墙、隔断墙、钢骨耐火被覆层、隔热保温层等。日本在1973年的加气混凝土使用量为160万米~3,同西德、瑞典等国家在一起,成了世界上屈指可数的加气混凝
Japan’s aerated concrete production technology was introduced from Sweden. Since the beginning of production in 1963, a kind of prefabricated plate that combines the properties of light weight, fire resistance, heat insulation and heat preservation has been rapidly popularized. It is used for roofs, floors, exterior walls, partition walls, steel fireproof coverings, and heat insulation layers of various buildings ranging from residential buildings to high-rise buildings. In 1973, the amount of aerated concrete used in Japan was 1.6 million m 3 , which together with West Germany, Sweden, and other countries became the world’s only aerated concrete.
