国家建材局中国建材制品工业公司于11月上旬在株洲市召开了“利用粉煤灰、煤矸石发展建筑砌块经验交流会。”1981年,全国共生产各类砌块180万立米,用砌块建房约300万平米。特别是利用粉煤灰、煤矸石发展建筑砌块对综合利用工业废渣、节约能源、保护耕地有显著的作用。按推广这两类砌块100万立米计算,可取代7亿块粘土砖,节约5万吨煤,少毁耕地700亩,可利用废渣100多万吨。在会议
The National Building Materials Bureau China Building Material Products Industry Corporation held an “Experience Conference on the Development of Building Blocks Using Fly Ash and Coal Gangue” in Zhuzhou City in early November. In 1981, a total of 1.8 million cubic meters of various types of blocks were produced nationwide. Block building about 3 million square meters. In particular, the use of fly ash and gangue to develop building blocks has a significant effect on the comprehensive utilization of industrial waste, energy conservation, and protection of arable land. According to the promotion of the 1 million cubic meters of these two types of blocks, it can replace 700 million clay bricks, save 50,000 tons of coal, destroy 700 acres of arable land, and use more than 1 million tons of waste residue.
