通过多年的科学研究,苏联利用干排或湿排粉煤灰可大量生产用于轻混凝土的人造骨料——多孔烧结砾石。全苏建筑材料科学研究所近年来对特洛依斯克俄罗斯中央发电站、克拉斯诺热电站、巴甫洛塔尔第二热电站等共八个热力发电站排出的粉煤灰进行了试验研究,考察其性能是否宜于生产多孔烧结砾石。这八个热电站都是由埃其巴斯吐产煤区供应同一种原煤做燃料的。 Through years of scientific research, the Soviet Union can use dry or wet fly ash to produce large quantities of artificial aggregate for light concrete, porous sinter gravel. In recent years, the Institute of Building Materials Science of the Soviet Union conducted a pilot study on fly ash discharged from a total of eight thermal power stations, such as the Russian Central Power Station, the Krasno Thermal Power Station and the Pagoltal Thermal Power Station in Troysk. Investigate whether its performance is suitable for producing porous sintered gravel. The eight thermal power stations are all supplied with the same raw coal as fuel from the coal-producing area in Echibas.
