日本国立住房有限工业公司联合研制成功全世界第一块大尺寸轻型陶瓷混凝土板。计划批量生产,目前正处于中间试验阶段。它属于加气混凝土,其表面象陶瓷釉般的完美,硬度可与瓷砖相媲美。已在欧美16个国家申请了专利。 普通水泥混凝土由于成分的分离,在500℃以上往往会损失其强度。研究人员发现,当在特殊条件下进行养护并在850℃的温度处烧结前涂敷一层釉,混凝土可制成十分耐热、耐化学物和耐候的材料。所制混凝土的表面
Japan National Housing Co., Ltd. has jointly developed the world’s first large-sized lightweight ceramic concrete slab. Plans for mass production are currently in the middle of the trial phase. It belongs to aerated concrete and its surface is as perfect as ceramic glaze and its hardness is comparable to that of ceramic tiles. It has applied for patents in 16 countries in Europe and the United States. Ordinary cement concrete tends to lose its strength above 500°C due to the separation of components. The researchers found that when applied under special conditions and applied a layer of glaze before sintering at a temperature of 850°C, the concrete can be made of a material that is very heat-resistant, chemical-resistant, and weather-resistant. The surface of the concrete
