各种轻型复合板材以其重量轻、保温性能好、抗震性能好、施工安装方便、能增加使用面积、降低劳动强度,建筑造价适中等特点,在我国经济较发达地区及大中城市不断涌现,并显示出勃勃生机。 1975年国家建材局在天津建材工作会议上提出:要大力发展轻质、高强的新型墙体材料,改革“秦砖汉瓦”,组织开发石膏板,加气混凝土
Lightweight composite panels are lighter in weight, better in heat preservation performance, better in seismic performance, easier to install and install, able to increase the use area, reduce labor intensity, and have moderate construction cost, and are emerging in China’s more economically developed regions and large and medium-sized cities. And show great vitality. In 1975, the National Building Materials Bureau proposed at Tianjin’s building materials work conference: We must vigorously develop lightweight, high-strength new wall materials, reform “Qin brick and tile,” and organize the development of gypsum board and aerated concrete.
