在毛主席革命路线指引下,我厂从一九七一年开始利用哈尔滨热电厂粉煤灰代替砂子和矿渣试制粉煤灰加气混凝土砌块。几年来,发动群众,自力更生,制造了蒸压釜与其它专用设备,建起了年产能力一万立米加气混凝土制品的生产线。通过生产实践和兄弟单位的帮助,现在已基本上掌握了蒸压粉煤灰加气混凝土的生产技术。生产了规格为485×300×240mm、 Under the guidance of Chairman Mao’s revolutionary route, our factory began to use ash from Harbin Thermal Power Plant in place of sand and slag to produce fly ash aerated concrete blocks in 1971. In the past few years, the masses have been mobilized and made self-reliant, autoclaves and other specialized equipment have been manufactured, and a production line with an annual capacity of 10,000 m3 of aerated concrete has been built. With the help of production practices and fraternal units, the production technology of autoclaved fly ash aerated concrete has basically been mastered. Produced a specification of 485×300×240mm,
