粉煤灰作为建筑材料已取得了较大的进展,如用作混凝土的掺合料、制砖材料等;而作为工程材料只是在最近才引起人们的重视。通过各种方法,如掺合水泥、石灰和土等不同材料,使粉煤灰性质得到改善后可广泛用于填筑路堤、路基和贮灰场堤坝等工程。特别是近年来公路建设的飞速发展,给粉煤灰的大量利用带来了广阔的发展前景。 Fly ash has made great progress as a building material, such as the admixture of concrete, brick making materials, etc.; as engineering materials, it has only recently attracted people’s attention. Through various methods, such as the blending of different materials such as cement, lime and soil, the properties of fly ash can be improved and can be widely used to fill embankments, embankments and ash storage sites. In particular, the rapid development of highway construction in recent years has brought a vast development prospect to the large-scale utilization of fly ash.
