粉煤灰——是从煤燃烧后的烟气中收捕下来的细灰。是燃煤电厂排出的主要固体废物,是我国当前排量较大的工业废渣之一;是具有火山灰活性的粒状材料,随着人们对粉煤灰研究开发利用的不断深入,粉煤灰综合利用途径趋广泛。目前粉煤灰在路桥工程中应用于混凝土、砂浆、筑路及回填等领域。从节省自然资源、减少废物对环境的危害等诸方面均有显著的效益和重要的意义。
Fly ash - is a fine ash collected from the combustion of flue gas in coal. Is the main solid waste discharged from coal-fired power plant, which is one of the current large-volume industrial waste residues in our country. It is a granular material with pozzolanic activity. With the deepening research and development of fly ash, the comprehensive utilization of fly ash Ways to broaden. At present fly ash in road and bridge engineering used in concrete, mortar, roads and backfill and other fields. From the conservation of natural resources, reduce the harm of waste on the environment, etc. have significant benefits and significance.
