粉煤灰是一种人工火山灰质材料,长期被人们视为废料,从七十年代起我国开始研究和应用了粉煤灰,实践证明粉煤灰是一种多功能的新材料,尤其在建材工业和建筑工程中发挥了重要的作用。我省煤炭资源丰富,燃煤的火力发电厂多,粉煤灰排放量大。据有关资料查明,1986年的排灰量达300万吨,利用粉煤灰只有48万吨,占当年排灰量的17％,预计2000 Fly ash is an artificial pozzolanic material that has long been regarded as waste. Since the 1970s, fly ash has been studied and applied in China. Practice has shown that fly ash is a versatile new material, especially in building materials. Industrial and construction engineering have played an important role. Our province has rich coal resources, many coal-fired power plants, and large fly ash emissions. According to relevant information, it was found that in 1986, the amount of ash discharged was 3 million tons, and only 480,000 tons of fly ash was used, accounting for 17% of the ash discharge in the current year.
