陶粒是一种人造轻骨料,其主要品种按所用原料分为粘土陶粒、页岩陶粒和粉煤灰陶粒等。近年来,苏、美等主要陶粒生产国将陶粒大部分用于墙体保温、高层建筑和制造轻质混凝土预制板等,其次用于化工、冶金、农业以及航空等高科技领域。 Ceramic granules are a kind of man-made lightweight aggregate. Its main varieties are classified into clay ceramsite, shale ceramsite and fly ash ceramsite according to the raw materials used. In recent years, major ceramic grain producing countries such as the Soviet Union and the United States have used ceramics mostly for wall insulation, high-rise buildings and the manufacture of lightweight concrete prefabricated panels, followed by high-tech fields such as chemical engineering, metallurgy, agriculture, and aviation.
