随着建筑技术的发展,建筑物趋向高层化和大型化,因此,减轻高层建筑和大跨度构件的自重,增加结构的保温隔热性能和提高建筑物抗震性能已显得十分重要,这些都促进了轻骨料的发展。目前全世界轻骨料的年产量在1.2亿 m~3以上,其中约3/4为人造轻骨料,天然轻骨料仅占1/4。天然轻
With the development of building technology, buildings tend to be tall and large. Therefore, it has become very important to reduce the self-weight of tall buildings and long-span members, increase the thermal insulation performance of structures and improve the seismic performance of buildings. Lightweight aggregate development. At present, the annual output of light aggregate in the world is more than 120 million m 3, of which about three-fourths are man-made lightweight aggregates and only 1/4 natural lightweight aggregate. Natural light
