我国新型墙体材料的生产应用始于20世纪六十年代初。当时是以工业灰渣——粉煤灰、煤渣为主要原材料,生产的中型粉煤灰砌块是我国最早的新型墙体材料,之后蒸养煤渣砖、蒸压加气混凝土条板,以及大型板材等,都先后建厂投产和使用。1975年原国家建工总局（建设部前身）总结我国新型墙体材料生产应用十多年的实践经验,第一次编制了以建筑工业化为中心内容的我国墙体改革规划,规划提出了大板建筑、砌块建筑、框架轻板建筑和混凝土现浇工艺墙板四种建筑体系,作为我国墙体改革中新型墙体材料的试行方案。当时国家建材局也提出了“621111”的墙改方案。
China’s new wall materials production and application began in the early 1960s. At that time, based on industrial ash - fly ash and cinder as the main raw materials, the medium-sized fly ash block produced was the earliest new type of wall material in China. After that, steam cinder bricks, autoclaved aerated concrete strips, Plates, etc., have set up factories and put into operation. In 1975, former State Construction Engineering Administration (predecessor of the Ministry of Construction) summarized China’s new wall materials production and application of more than 10 years of practical experience, for the first time compiled a building industrialization as the core content of China’s wall reform planning, planning put forward the board Building, block building, light frame construction and concrete cast-in-place process of four kinds of building wall system, as China’s wall reform in the new wall materials pilot program. At that time, the State Building Materials Bureau also proposed a “621111” wall reform program.
