| Abstract: | The cement pavement in highway has special requirement to function of concrete. It demands that concrete owns not only good physical properties but also high resist-breaking intensity. The function of putting the powder coal ash into the concrete is studied in this paper. The technology about how to make the powder coal ash, the amount of powder coal ash, design method of suitable proportion is discussed. |
