近年来随着我国火电建设的不断发展,其主要工业废渣——粉煤灰也在迅速增长。专家认为,大规模开发粉煤灰在建材领域中的应用,是粉煤灰利用的一个积极有效途径。 据预测,到2000年,我国粉煤灰的年排放量将达到1.6亿t,累计堆存量达22亿t,占地面积达44万亩。目前,国外发达国家 In recent years, with the continuous development of China’s thermal power construction, its main industrial waste residue, fly ash, is also rapidly growing. Experts believe that the large-scale development of fly ash in the building materials field is an active and effective way to use fly ash. It is predicted that by the year 2000, the annual emissions of fly ash in China will reach 160 million tons, and the cumulative stockpiling volume will reach 2.2 billion tons, covering an area of ​​440,000 mu.
